There are lots of reasons it could be preferable to centralize. OTOH their mission is limited and some competition is healthy, if only to explore alternative ways to do things.
PG focuses on an accurate digital translation of the source material, sometimes hosting multiple different versions of the same text, and doing things like putting work into recreating the adverts at the back of some novels.
SE focuses less of preservation and more on making readers’ versions of the texts, like other publishing imprints. So there’s typography standardisation, a light-touch moderinisation of hyphenation and soundalike spelling, and things like author-wide collections of short fiction and poetry even if it didn’t previously exist.
Both are valuable, but they serve different segments.
When I read an old novel, written two centuries ago in England, the little differences to modern English are part of the charm, and I certainly don't want any Americanism mixed in. For one of my favorite novels, The Forsyte saga, the author deliberately used some rare forms of words, which SE replaced with the mainstream forms.
The only thing they are is truly, truly wonderful.
The Bible is I daresay the most famous of these. Translations aside, even the English versions have had significant alterations done to wording, spelling, and meaning depending on the version.
There's also the Great Illustrated Classics imprint for certain classic novels like H.G. Wells's The Invisible Man. (I read that one like 10 times as a kid and it's what got me into sci-fi as a whole I'd argue. Haha.)
Whether these alternate versions are good or bad is obviously up for debate and depends on the person, but I'm just saying that what SE does is hardly new in the publishing world.
I personally worked on the Forsyte saga. If you think something was done in error, please let us know and we'll be happy to fix it.
Curious. Why even bother?

The edit is still in place, and I still maintain that changing 'phone to phone in dialogue changes the meaning.
I also have many positive things to say about Standard Ebooks, but I don't think you were asking about those. :)
More broadly, the position of Standard Ebooks is that a modern reader would be distracted by spellings like "some one" and "every thing", and by time written like "2.30" instead of "2:30", and that books in British quotation style must be converted to American quotation style. I think most readers can in fact tolerate such small differences, and this position is frankly insulting — the punctuation and spelling of works are part of their character, and if anything, I'm more distracted by such anachronisms in style introduced as part of the Standard Ebooks process.
But nearly all print publishers also do what SE does. Why do you think they do, when it costs additional money and time to do that? A reasonable answer is that some, or a majority of, people prefer it.
Do they? To check, I tried to find a recent publication of Agatha Christie, and found the collection “Country Christie: Twelve Devonshire Mysteries” which says “First published by HarperCollins Publishers Ltd 2025”. It still has British-style punctuation (throughout the book), and times like “1.30”, “9.30”, “11.30”, “7.30 a.m.”, “12.30 p.m.”, and “8.30”. I checked a couple of other recent publications and admittedly they do modernize (though not in phrases like “every one of you”), but again I found the collection “The Last Seance: Haunting Tales from the Queen of Mystery” (2019) which does not. So it seems mixed.
In any case, I think it's fine to do what Standard Ebooks does, and if it were instead called something like “Modernized Ebooks with American punctuation”—if readers would know before picking one up—it would be totally unobjectionable. The name “Standard” gives the wrong impression. It's a bit like colorizing old black-and-white movies (or dubbing foreign-language movies instead of subtitling them): yes possibly even a majority of people may prefer it, but IMO it would be good to be more explicit what has been done.
I have very mixed feelings about Standard Ebooks and would much prefer being able to use Project Gutenberg directly, but one good thing Standard Ebooks does is that every book has an associated git repository (on GitHub), so it's (in principle) possible to see a history of fixes to the text over time.
