IIRC they don't make anywhere near $10/user/month. If you gave me the option to pay, say, $25/year for ad-free, tracking-free, and it was implemented in some way that I could trust, then I might be willing to participate with FB again. I'm hoping, actually, that someone will come along with exactly this business model so that we can have social networking for friends and family without the dark patterns. Needs to get everyone on board, of course, which is the hard part.
