He's fully aware. There is a good chance that the alleged new owner isn't quite as proficient in English, and posting via Google Translate / ChatGPT is cumbersome.
I don't think that's the reason, as Ratimov also used google translator, like more than half the forum nowadays.
It might be noticeable, if Ratimov knew some English and the current owner hardly any, in the corrections to what google translator writes by him before publishing the post, which might sound more natural, but I think it's more because of everything that has been discussed in the thread I don't think the linguistic issue is the most relevant.
