That's something that drives me crazy as well. I don't actually use the big 'algorithmic social media' sites, only Telegram and Discord mostly, and seeing screenshots/memes with those words censored there made me wonder why, at first. Then i saw people auto-censoring themselves in those places where there's no such thing as algorithmic de-ranking. The social media generation already find it normal, acceptable, and is specially ironic to me that a lot of people who are vocal against those services have conformed to what they say to stand against.

That behavior also highlights how people within those services care so much about reach, clout, 'going viral', instead of communicating with other people.
