> it already became very fashionable to call GitHub "ShitHub"

I talk to a lot of people developing both open-source, and proprietary software. Some of those are on GitHub, others on SourceHut, others on Codeberg. I have never heard, not even once, a single person other than you use the word ShitHub.

Maybe it's used in some obscure circle you are in, but it's nowhere close to fashionable.
