Well I think about 50-100 million users in world would be looking to have paid account. Since those are valuable customers who would definitely not want to have invasive, tracking advertisements and advertisers definitely want to target them. The only way it would work is if FB totally does away with advertising.

With current numbers the way it could work is if those users make annual commitment of at least 500-1000 USD or 200-400 dollars / quarter.

So the users with loud ethical voice and concerns about negative affects of advertising can save the world from this whole tracking business by committing about 1000 dollars a year.
