> If browser vendors simpy start disabling browsers, we have much bigger problems.
There is enough competition in the browser market that selectively disabling certain sites will lead to a big loss in market share, and would be an exceptionally stupid move.
Crushing apps is not a big problem (Zynga still earns more than facebook itself). The problem is we cannot sign an SLA, or have any other contractual relationship with facebook, even though they take a 30% cut or ouf virtual currency sales.
Still, for a company that is essentially a parasite on facebook, the money they earn is staggering. They could even earn a lot more if they used advertising on their games (they stopped using ads in 2010).

Facebook's interest is in policing apps, and acquiring/crushing/copying the relevant ones.
