Matrix user of almost a decade here. A PluralKit-like project actually does exist, a friend/ former partner of Ours developed it.

They are no longer on Matrix, and We wish We could follow suit. Do not use Matrix, it is absolutely not a safe space for marginalized folks by any stretch of imagination.

We know this because We were the defacto head of the last public safe space that was left standing, a feat only accomplished by terribly dedicated helpers (mods) and programmers who would make custom tooling for that community. It wasn't enough.

See, not only is Nev Vector Inc. very corporate oriented, they're actively hostile to community contributions. You can loudly yell about flaws that are easy to abuse, or make full code submissions of things that have been hotly requested for years, and it will be entirely ignored, if it doesn't directly align with their corporate interests.

Right now most of those who remained are scattered in a new community that's bridged between Discard, which at least does something to prevent the worst cases of abuse, and Revolt, which is still a pretty basic project feature set wise, compared to Matrix and Discard, but you can tell that it's made with actual care, it's also EU based.

Yeah, this lines up with what we've heard from a number of other people, sadly... that Matrix has been more interested in pandering to cops, governments, and corporations rather than building safe and respectful tech for everyday people. And that yes, you could self-host, but that it's a nightmare that they have no intent of making easier because it would conflict with their managed hosting services. Not to mention ongoing issues with metadata and loopholes that can be used for abuse. Unfortunate.
