People keep saying that. Like it's something that actually happens. And let's be clear, it has happened with a number of commercial products. But Microsoft and others have never managed to EEE email, HTTP/HTTPS, Usenet, Linux, Java even. And they've tried haaaaaaaaaard. Google didn't EEE XMPP either. It still exists. I use it daily. The author is misrepresenting what happened.
What happened is that too many people felt obligated to work with corporation that had little interest in working with them. Rather than to focus on their own system and continue to update or develop it. Neglecting their core user base, chasing after people who didn't seek it out and didn't care what they were using so long as it worked. They wasted time and effort. But Google didn't actually kill anything. And all the people using Google talk typically weren't interested about XMPP in the first place and never would be.
It goes beyond that even. Lemmy is developed by socialists. And not just the more reasonable bunch of socialists like myself. But straight up militant leninists. They're part of the core development team if not the whole thing. And they have no interest in catering to or coddling misbehaving corporations. They are going to do what they want and what they feel they need to do when they need to do it. And if meta or anyone else tries to screw it up. They're not going to pay one single bit of attention to them and just keep on doing what they've been doing
