There is no large audience in any developed market willing to pay $15+ per month for Facebook just to remove ads.
The problem is getting from zero to critical mass with that model. Though I guess that doesn't stop a lot of other companies with less plausible revenue sources from getting seemingly endless money thrown at them.
Don't get me wrong, I don't think it would ever work, because I may value my privacy at more than a few bucks a month, but it's a near certainty that the vast majority of the population disagrees with me. They don't see the cost there, so they ignore it. By the time they ever realize what it was they gave up and for how little, it's too late.
But you just said you just need your family and some friends. That doesn't sound like critical mass is needed. Just convince your family and some friends to join with you, and enjoy the service together. Then your friends can invite their friends and family, and so on and so forth.
Yeah I understand the goal of capitalist companies is to endlessly print more money for the shareholders and the promise of ever better advertising enables FB to keep pulling in the dough. But maybe something like social media shouldn't operate in that context.
Just in case, FB ARPU in US in Q4 2017 was $27. People who talk about "i ready to pay 10$ per year if im not tracked and not exposed to ads" _seriously_ underestimate FB money-printing ability.
Think about it, FB makes almost as much as NFLX per US user (admittedly in Q4, the hottest quarter in advertising), but you dont need to enter your credit card. At all.
