Intensions do not metter in this case. It can be used for that and that’s enough. If you block any connections that use ECH (by blocking cloudflare-ech for example) users will have no choice but to fallback to unencrypted CH.

I doubt it. Today there is a huge trend towards censorship in the world. And ECH is exactly what a censor would not want. It is already blocked in Russia after Cloudflare enabled it by default and I would expect it to be blocked in the west “for anti-piracy reasons” very soon.

Try starting with dbus session. Also try lxqt-session and startlxqt commands.

Because it is affiliated with gnome…
