Hieroglyph are pictograms/logographic scripts. One word for one logogram to represent one word.
They mostly talk about the fact that the Phoenician may have come from illiterate worker in the Canaan mines. Unable to learn hieroglyphs, they may have invented a simplified writing system leading to the Phoenician. The main interest is that the Phoenician abjad is not a construction from savant but by illiterate workers.
What do you mean by count? Various writing system exists in parallel, none really prevails on the other. Egyptians did not have an alphabet per se like Mandarin do not really have one either at least not really one that is reflected in the writing system.
Neither are Chinese characters, BTW. Chinese is a syllabary, but with a lot of redundancy -- 1200 syllables, lots more characters -- and arbitrary, historical rules about which variant for a syllable may be used for each word.
Amazingly (at least it amazes me), most Mandarin speakers think that other Chinese "dialects" are just different ways to pronounce Mandarin, where in fact they are as different from Mandarin as various European languages are from Latin.
Many even think of the characters as pictograms with complicated rules about sharing with homonyms. People who know more than one Sinitic language know better.
That is what is so amazing about monolingual Mandarin speakers believing they should be.

1. Save for 係, 嘅, and 喺, the former is perfectly valid Mandarin. Every other difference between the two texts are phrasing differences from then being written seperately by different people. If you did s/係/是/, s/喺/於/, and s/嘅/的/ and copy pasted the Cantonese version into regular Chinese Wikipedia nobody would notice.
2. Despite the fact that not a single word in those two excerpts would be pronounced the same, you can clearly see the same characters being used even if you can't read Chinese. This can not be the case if it were a "syllabary".
3. 係, 喺, and 嘅 are written differently not because they're pronounced different(so is every other character in the above excerpt) or even because they have a different meaning(they pretty much serve the same grammatical purpose as 是, 於, and 的), but because they have different etymologies and are different morphemes. This can only be the case if the writing system is logographic. It wouldn't be the case in either a logographic or ideographic system.
Mind you Cantonese Wikipedia is written exclusively by people like you who think Cantonese is a "language", and it's not some dying dialect(It's the second largest dialect and probably spoken by at least 50% of Chinese speakers who actually use Wikipedia and not some other wiki) like Scots so you can't claim that the people writing are just bad Cantonese speakers.
Spoken Chinese does not, and an accurate transcription of colloquial Cantonese is quite different from colloquial Mandarin: 係唔係佢哋嘅 vs 是不是他們的, and that's despite the grammar of the two sentences being identical (which is not normally the case either).
But even then your example is far more cherry picked than mine. Translated your phrase means "is it not theirs". It doesn't have any common nouns that aren't pronouns, adjectives, or even a verb that isn't is/是/係. You also managed to do something I couldn't even and provide an example where every word had the same exact grammatical meaning and were arranged in the same order in both examples. Really helps my point about logography more. If Chinese were ideographic and not logographic those words would be written the same. They're not because of differing etymologies.
The fact that you can only find colloquial examples that are significantly different is why it's a dialect. AAVE or Appalachian English are also near incomprehensible when spoken/written colloquially. Hell, I could even make the dumb arguement that liberals/conservatives speak a seperate language with something like your example. "was he Latino"/"were they latinx?"
Here I found the following sentence on a Cantonese bbs.
"推普滅粵係中國政府堅定不移的國策"
Perfectly valid Mandarin except for 係/是. You can't claim that a bbs comment complaining about the promotion of Mandarin, written on a forum dedicated to Cantonese of all things is formal language that's "tending towards" "mandarin".
So I guess the real answer here is that the Egyptian writing system incorporates elements of alphabets and logographs, used together. Vowels were (mostly) not marked, though some "consonants" are treated as vowels in transliteration. I'm not entirely sure what the distinction is there.
My understanding is that it was an abjad, not a syllabary. An abjad has only consonants, not vowels. When a word is written, only its consonants get written, and the vowels are only implied. Hebrew and Arabic are abjads.
The Phoenician alphabet was preceded by the Ugaritic "alphabet", which was also an abjad.
A syllabary usually has many more symbols than an abjad or alphabet. If n denotes the number of phonemes in a language, then a syllabary has O(n^2) or O(n^3) symbols. In contrast, the Phoenician abjad has fewer symbols than even the English alphabet.
The earlier, unknown, abjad, must have been used to write the same 27 consonants as in the Ugaritic alphabet, but using graphic signs similar to those used by the 22-sign Phoenician alphabet, which resemble in form the Egyptian signs.
There is no doubt that the Egyptian writing system was the inspiration for the first abjad, because both the method of writing only the consonants and the direction of writing were inherited from the Egyptians.
In Ugarit, in order to write on earth tablets, like in Mesopotamia, the original graphic signs used for the 27 consonants were replaced with cuneiform signs.
On the other hand, the Phoenicians deleted 5 letters, because their language was simplified and the 5 deleted consonants were eventually pronounced identically with other 5 consonants. It is supposed that the Phoenician pronunciation was simplified so much because it was used as a lingua franca for commerce, by many people.
This reduction in the number of consonants created later problems for other Semitic people, e.g. Hebrews and Arabs, who still pronounced distinctly some of the consonants that were deleted from the Phoenician alphabet, so they had to invent diacritics to mark the missing consonants (e.g. shin and sin in Hebrew).
Although the Ugaritic and Phoenician alphabets come from the same area, they are discontinuous. However, the ordering being roughly the same, and following an earlier Egyptian ordering, is the big hint that they share at least inspirational descent from the same source.
Why that area of Lebanon? Byblos has been an Egyptian colony in that region for a very long time (~4600 years ago), ensuring continuous scribal presence. Scribes of that region are noted for intense multi-lingualism (as perusal of Ugaritic tablets is evidence of), so cross-pollination of scripts makes a lot of sense.
I haven't read through Goldwassers papers, but a lot of what they quote in the article seems to be unnecessary to explain the transmission of the abjad.
The difference is just that 5 consonants are missing from the Phoenician alphabet in random places: between gamma and delta, between kappa and lambda, between mu and nu, between nu and xi, and between sigma and tau.
It is known with which other consonants the deleted consonants were merged. For example Ugaritic had "s" and unvoiced "th" like in "thin", while Phoenician pronounced both as "s" and kept only the sigma letter.
(I have used the names of the letters as used by the Greeks, as those are more familiar for most people)
The Ugaritic alphabet also used for certain purposes 3 supplementary signs, invented later, and which were added after the original 27 consonants.
I've no idea how well that story is supported, but abusing new technology for purposes it was never intended to fill does seem like an eternal human fact.

Are they using "alphabet" in an informal sense, in the article, to include syllabaries? Or am I misinformed?
And then, what are the hieroglyphs? Are they just talking about the specific set of letters we call our alphabet, and not the idea of an alphabet, which surely the Egyptians had? Unless that is itself a syllabary, and so doesn't count?
