Outside of human based moderation the real issue is that Facebook is deciding what will people see on the feed all the time. People somehow try to liken Facebook to post office, or whatever, like it's some dumb pipe. It is not.
Facebook shows you from the feeds of your "friends" whatever the company decided. Probably based on some algorithms, but it could be millions of cats rolling over the keyboards for it's not public what Facebook really does.
Third parties analyze and weaponize this behavior for many things from comercial interests, to justifying murder, to incitement to violence.
Facebook needs to be held responsible for its algorithms. Somehow. Stupid autonomous car makers will eventually be held accountable for their algorithms too. It's not like they can put some crap in their EULA and be done with it.
PS: Add to it that Facebook is the internet in some places. It's not just one of the websites.
Uniform platform support for multiple architectures. I have Linux desktops on i686, x86_64, arm and aarch64. Same desktop environment, same programs, same easily mirrorable configuration, same firewall system, wireguard, same or fairly equivalent package management between systems.
