BTW, I found further stupidity earlier this week--I had to use their terrible forum to ask a plugin developer a question. The login has a checkbox to certify that I am not part of WP Engine.
Sadly this isn't new. And a number of people have walked away because of it.
but who knows how much longer WP will be around? Matt could decide to pick up his toys and go home and shut it down.
There's enough money on the table, enough people depending on it that it won't go away any time soon.
WordPress, the core software, is GPL-based, forking is entirely possible and I rather suspect if Matt takes his toys and goes home, the community will do something about it. (More or less successfully, that is. ClassicPress's existence proves that forking needs to have more of a goal than 'not this' where the majority adopted WordPress with Gutenberg, rather than ignoring it in favour of sticking with the classic editor.)
What, however, is very up for debate is the ecosystem. Matt has made it clear that wordpress.org is owned by him, personally - not the WP Foundation. He can take his ball and go home and pull
all of that down overnight. And that is a much more significant question. WP's continued adoption relies predominantly on its ecosystem, and if you fragment that by making people have to go to different places to get updates, that's going to be problematic.
Now, the community has already recognised this and efforts are already underway to do something about this (see AspirePress) but the general mood seems to be that this is going to go to court and Matt is going to have his butt handed to him, and he'll take the hint. That's the hope, anyway.
WPE don't even have to say or do much at this point - never interrupt your enemy while they're in the middle of making mistakes. And the last filing that went in just kept pointing out the latest things Matt was saying, because he is absolutely his own worst enemy here.
