Who made this? I’d like it if it said Matrix is federated, Signal is not. Meta should be clearly grouped together. Aren’t there other alternatives to Reddit than Lemmy, so there should be more arrows going out of Reddit?

The email comparison is broken and should include “in principle” and then continue with “in practice [real situation]”. This is a start:

I like the yellow bubble here, but it’s inaccurate in many ways:

• Manipulation can be done by outside forces making fake users, not Fediverse programmers.
• Censorship is done by server administrators and community moderators, but (on Lemmy at least) posting community censors your post, not your home server. Might show a scale where lemmy.world is at the strict end.
• Your votes are public, you can be tracked, but it’s not done by default.

A normal person will have to mute tens of communities for the feed to start looking tolerable. This is one of the many prices of freedom you will have to pay, as are bugs and user experience issues. (AFAIK, no fedi platform uses votes for feed shaping, but many commercial ones do.)
• The choices between apps or web-ui should be shown for each fedi platform.
