I think what Facebook is fundamentally missing is interoperability. Imagine if Gmail users could only email other Gmail users. If Facebook allowed other services to be fully interoperable then competition and choice would solve many of the other problems. Unfortunately Facebook is so dominant that it's not in their financial interest to allow that, so the only way I can see it happening is if the government steps in and forces them to.
