>I fail to understand why is this a 'problem'. FB can do as they please (fail or succeed as a consequence), they aren't a tax payer funded institution answerable to the public at large. In effect, people are dictating how FB should 'run their business'.

Much like the Microsoft anti-trust suits of the early '00s? There was nothing then (just as there is now) that forced people to use Microsoft products; numerous OS and software alternatives existed.

Facebook is currently large enough to distort industries and markets, just as Microsoft once was.
