By claiming Instagram and Camera as its own, Facebook might block another company from launching a competitive service. Even if somebody else does, Facebook will likely have secured a foothold in the area. If a Facebook user leaves the site and heads over to Instagram, assuming it remains independent, the service still hangs under the Facebook umbrella. Whatever revenue Instagram ends up producing, it's Facebook's. The company also acquires one of the fastest growing social media sites, flush with all types of talent.
