You shouldn’t crap on people being honest about the problems that have existed,

I haven't "crapped on" anyone. I just pointed out that a comment, which was an absolute declaration in present tense, is misleading, poorly informed, and needlessly quarrelsome. Because it is. And the author then tried to justify it by putting words ("has always been") in someone else's mouth. None of that is honest. It was arguing in bad faith, and it's important to call that sort of thing out, because letting it go is how misinformation spreads.

If they had instead just presented their view as historical experience to help inform about track record, I wouldn't have taken issue with it.

Too much in the open source community is people saying this is great!

Perhaps, although that's common around proprietary software as well.

Great is subjective. Matrix has struggled with some problems that rightly frustrated people, but it also has accomplished some things that no other messaging platform has. By that measure, it is a great project. And the announcement we're all discussing here demonstrates that it is getting better. Just as barkingspiders said.
