@palllyyy I missed a few items.
Important to me is no algorithm. I turned that of in X with FF extension Control Panel for Twitter.
Mastodon is open and can be viewed without an account.
Mastodon toots can be edited afterwards.

I stil have an account at X, be use it seldomly. Unfortunaly a lot of importantant (local) persons remained on X. Never had bad experiences on X, due to filtering/blocking certain words. Do that also on Mastodon.
