Here is another one. Artscroll was criticised for publishing the Gemora in English, the everyday language in the US. Yet the Gemorah itself was written in Aramaic, which was the everyday language of the people in Bavel
The objection you’re referring to should/would have already existed with the Soncino edition. Did it? That’s a genuine question – not just a challenge.
Perhaps more research into the origins of the objections wouldn’t hurt; the letters are documented.
Not to do with Artscroll in specific, but R’ Yaakov Kamenetsky even objected to the suggestion of printing gemara in the original Aramaic with punctuation (his reasoning is in print).
