Third option: Facebook changes it's business model from data gathering and selling to pay-to-use. Make Insta and FB both be gate communities where folks have to pay to post.

Fourth option: product becomes less addictive and the algorithms stop optimising on "angry users click more". Less advertising profits, perhaps less engagement but probably still profits on advertising.

Fifth option: don't aim to continually increase profits and instead change the rules of capitalism to be less focused on making "profit at any price" to perhaps a more gentler form. After all, Monopoly(TM) is restarted once one player has all the money, it's about time that we do that in real life too or how many more trillionaires do we need?

So there are also grey choices here and not only b/w.
