Facebook might even be okay with that, because they'll be making the same amount of $$ and could potentially charge you a premium. But it will be hard for Facebook to sell it's advertising customers on a reduced pool of eyeballs; and I bet statistically people willing to pony up $10 to avoid ads are also likely to buy the products advertised on Facebook (i.e., I think people like you or I and many others on this site are outside the norm).
