That would make sense, but language unfortunately isn't obligated to make sense.
In English, "America" unequivocally means the USA. "North America" unequivocally means the continent, and "the Americas" means both continents. This is only a problem because of clashing language and geography standards--in some languages there's only one continent and it's called "America," so it's easy to have misunderstandings between Spanish and English speakers using the same word to mean different things. But neither one is wrong. They're just speaking different languages.
(Neither is wrong about the definitions of the continents, either. Continents are arbitrary and always have been.)
I do agree with that, but for a language such as English, spoken all around the world, no one country or group of people gets to decide the meaning of words.
Insisting other people use your definition that you admitted doesn't make sense and making snarky comments like the article author did when they don't comply sounds pretty childish.
> In English, "America" unequivocally means the USA.
That is an extreme claim. As a contextual example, the gadget creators were apparently fine calling their gadget American.
Yeah, ... Nah.

Pretty much the only people who beleive that anything in English is unequivocal are those from central north american regions raised on prescriptive dictionaries and grammars.
Other english speakers use descriptive guides.
United States of America -> America
United States of Mexico -> Mexico
Republic of France -> France
Kingdom of Norway -> Norway
People's Republic of China -> China
Commonwealth of Australia -> Australia
Federated States of Micronesia -> Micronesia
Republic of South Africa -> South Africa
Republic of Korea -> Korea
Do you begin to see the trend here?
Note that the Federated States of Micronesia does not include all of Micronesia -- there are several other countries in that geographic region. Nor does the Republic of South Africa include all of South Africa. Nor does the Republic of Korea include all of Korea.
Besides, the USA was the first, and so far only, one to use "America" in its name, so it gets grandfather rights.
