Unfortunately it seems like they make a lot more money per US user than that now:

($53 per US user)

Facebook annual revenue is ~$47/daily-active-user . The number for US users is comparable.

Notably, however, a competitor need not target the same level of profitability.

Now, whether asking users to pay for a social network at all is a viable business model, is another question.

I’d pay $12 a year for a Facebook free internet.

If you are seriously considering paying for the poison that is Facebook, might I recommend you delete your Facebook account instead, and give your money to someone that needs it?

You know that you can blackhole all facebook domains and enjoy facebook-free internet today?

Maybe OP is suggesting everyone pay $12 to take down Facebook? The method needs articulating as everyone on earth paying US$12 wouldn’t get close to buying them out and shutting them down.
