As part of the ongoing enshittification of the internet, tragedy of the commons etc., these big centralized internet platforms decided that instead of being responsible and making their products *slightly* less terrible it was better to maximize short term engagement metrics, and that, egotistically, the chance of there being real consequences for their actions was near zero. (Or, even more cynically, that their yearly performance review was more important).
Now I'm afraid they've screwed everyone over and the idea of an anonymous open internet is now dead- we're gonna see age (read, real ID) verification gating on every site and app soon....
The dumb thing is to look back and see how umimportant it is that Facebook feed algorithm be this addictive. They already had the network effects and no real competitors. They could have just left it alone.
