The problem is not Facebook or Meta. The problem is the disgusting business model of targeted advertising coupled with algorithmic curation of content to increase ad impressions. Facebook happens (happened?) to play that game perfectly but it's not limited to them by any means and another player will just take its place if Meta dies.

I'll keep my bottle of champagne for the day targeted advertising is regulated away, either on privacy grounds or on "Section 230" grounds (if you're curating content to increase engagement it's fair that you should be considered an editor and thus lose Section 230 protection and start being liable for any inflammatory content you promote to increase engagement).
