Seems to be a pretty big nail in the coffin for them and this is just the tip of the iceberg. lol. A class action of one of their core revenue streams is going to be very expensive. I think we should just make Facebook a public utility, and do them like the utility companies were done; congress can easily decide to transfer control of the company and all of its assets in a single resolution. Then, drastically reduce headcount by getting rid of all the business teams, sales, marketing and keeping only essential technical and administrative staff. Sell off the other unrelated business units (Oculus etc). Allow the company to operate and make a minuscule profit margin while allowing the local governments decision making ability regarding the content and policing of the networks under their geography.
I'd like this more than the status quo, but this still leaves the door open for governments to read private messages and leverage social platforms for manipulation. In my mind, and I admit I am not certain this is possible - the only right way for a social network to function is for it to be decentralized and user data controlled by individual users - with optins for any "sharing".
Other than that you hopefully can't do that without having to pay a massive amount of money under imminent domain laws, it now means everybody has to pay for Facebook, and that it will improve (if at all) at the level of congress.
