If I remember correctly, Apple makes it really hard to bridge iMessage and they implemented some sort of hardware check and even disallowed older versions of MacOS or so. As usual, they really like to lock people into their ecosystem.
P.S.: something is wrong with that link you shared.

I mean yes, Microsoft and slopcode probably plays a role, but it only got really bad once the LLM mass scraping started, for which I assume Github is also a major target.
And running your own public git forge is a real PITA these days for similar reasons.
