Wayland had/has a couple of missing features. Personally, it’s nothing I use so I’ve been on Wayland for years now, but if you care about those missing features, then they won’t work.

Honestly I don’t even remember what they were anymore. I think screen capture was a big one though.

I don’t think it’s really considered very safe anymore, although it is still very popular.

Afaik the Colorado thing wasn’t a hate crime, it was an act of terrorism. It was motivated by political cause (antizionism), not identity (Jewishness).
