Exactly. Plenty of engineers work on making military equipment better at killing people too. Some of them are software engineers. Facebook might seem like a moral blackhole to some but they are barely grey or neutral on the world stage of evil empires. An blind and bumbling giant perhaps, but not a purposefully evil one.

Algorithms is where the attention needs to go. The regulation probably needs to target the techniques Facebook and others are using rather than the organisations. It's the same crap as lootboxes in games training people to gamble. Newsfeeds and engagement optimization leads to attention grabbing and rage baiting posts. Just give us back the simple date based feed like Instagram has. Cut the algorithm weighted ordering. That's not everything solved but a lot of the overt manipulation of people is based on that.
