because the killer feature of facebook is staying in touch and meeting people. the path to monetization and revenue burned those features and overloaded them with spam and shit no one wanted. it got to the point where people stopped using facebook to meet and stay in touch with people

a similar pattern is happening on instagram although to a lesser degree

the metaverse bet is a good one to try and make something new where the value requires you to be on the fb platform. we will see if it works. i personally don’t see it going anywhere
