Saying that the reason FB is being targeted for anti-trust is that they are simply too successful feels like a vast oversimplification of the situation.
True, but I hear these conversations brought up against every tech company, regardless of what they are doing or why. Amputation may be a valid prescription for a patient, but if amputation is always the prescription, I may assume we are diagnosing wrongly.
No you don't. No one is pushing to break up Basecamp, or LinkedIn, or even companies that have actual documented histories of anticompetitive practices, like Oracle. I haven't even heard much chatter about breaking up Apple, altho that might ramp up as they move farther away from hardware into services and other areas. The conversation centers around FB, Google, and Amazon, for reasons that are unique to each of them.
Are you saying that breaking up the company is always the action from an antitrust case? That's entirely wrong. See for instance the antitrust actions against IBM leading to the 1936 consent decree and the 1956 consent decree, which changed IBM's behavior but didn't break up the company.
