Thank you so much.
We know that, in the most recent year, with Elon Musk taking over Twitter, part of why he has reinstated so many previously banned accounts is to try to build up revenue, and many advertisers who have departed that platform have done so because they've seen that their brand content is featured next to horrific, hateful, white supremacist, neo-Nazi content. On the question of who benefits, I'm not sure. Elon Musk surely has not, and Twitter is now valued at less than half of what he bought it for over a year ago.
There are other benefits, though, and many of the companies are benefiting because of ad revenue for eyeballs in other contexts. When Meta realizes that its revenue comes primarily from eyeballs that see incendiary content, they are boosting that type of stuff and pushing for users to see the most controversial content, because they know it will get more attention, more engagement, more likes, more comments and more shares.
