I'm all for capitalism but there comes a point where there needs to be balances and checks in place. I mean you already control so much information and 22% of the worlds referral traffic comes from Facebook. They have more than enough to monetize.
If they were to adopt a currency or currencies that are overlayed in its system and they host nodes or whatever cool but having your own currency on a system where there are data scandals, algorithms running wild and censorship with clear favouritism its just a recipe for disaster.
If they cant be stopped then sure go ahead and it will be up to the people to say no this isn't what we want, which I doubt, sheeple will be sheeple and fb shareholders will continue to get rich
