[edit]: to elaborate, I was under the impression that the whole point of anti-monopoly regulations was to protect consumers from monopolistic predatory practices, not to prevent monopolies from actually existing per se.
Hence my question: is there anyone actually being hurt by the currently limited choice of search engines or phone operating systems?
Also, what prevents someone from trying to build a much better one?
If Google starts to misbehave as a monopoly, fine, let the USG (themselves a monopoly, btw) do their thing go after them.
But as long as they provide a superior service for free (yeah, I know, you're the product, blah, blah), I'm not sure I'm seeing the problem.
