3--One of the things that is worst about Facebook and Twitter is that their algorithms decide what you see, not just your contacts / subscriptions list. Accepting a contact request or following someone is your affirmative choice to have that person's content in your feed, but they actively interfere with that. Sometimes for "engagement" raising (putting posts with extreme political positions in your stream so that you are compelled to react), sometimes for direct financial gain ("sponsored tweets" injected in your stream because an organization paid to have them), and now they also do this to prevent users from believing the wrong things.

In my view, this is dangerous and wrong. I know Eugen means well, but it is not your Tootmaster's (Mastodon admin's) place to decide what you are allowed to believe.
