"There comes a point that it is simply better to place your sales through Amazon and ebay, and circulate your news and promotions exclusively through Facebook and Twitter, as you know none of these will ever be filtered."

Even this is a dangerous opinion. The worst kind of censorship is self-censorship, where just the threat of being filtered causes organisations to self-filter far more than the government has ever asked for, because the boundaries of what is acceptable have never been defined.

You can say "they'd never block facebook", but just the threat of a government mandated social network is enough to get facebook to do what they want.
