Well, here on HN the intention seems to be to, to have interesting discussions. That works for me and other social media I do not use.

Except well, various messenger to be in contact with the groups and people I choose with no engagement algorithm deciding what posts I see, simple chronological order.

I'm curious how well influence campaigns work on platforms like Mastodon, or even BlueSky. They are, likely, not sourced from the platform providers which is definitely not the case for FB.

What do you mean, "as opposed to"? Yes, there are other scumbag billionaires weaponizing their social media platforms to ruin society. No, that doesn't make Mark Zuckerberg a better person.
