People make throwaways all the time for services like this. I expect lemmy to be no different.
Monthly active users would be a better statistic to track imo. That gives you a real idea as to how big the community is.
Anecdotally, content wise does seem better than a few months ago. Unfortunately lots of it seems to be highly polarizing and hateful stuff when you look at all communities. Othering seems to be as strong as ever, if not stronger. Probably because hate groups can just setup their own instances or take over parts of existing ones without much blowback like they would get on other sites.
I don’t think the movie in any way calls for eugenics.
If anything it called out how toxic ignorance and stupidity can be in the presence of someone who just wants to do the right thing. It shows how corporate greed and capitalism encourages stupidity to further it’s goals of creating basic labor for the corporate machines owned by billionaires to exploit.
But hey, that’s just like, my opinion man.
