The problem isn't so much having too many distribution services but rather that each service has a monopoly on specific content.

If each service had access to the same content as every other service then market forces would not only satisfy the price argument but also the quality of the services itself (lets be honest, some of the pirating services run circles around the legitimate ones).

Unfortunately though, the movie, TV and music industry have been allowed to operate monopolies - even push for extensions to copyright law and against reforms - for so long that I can't see it ever changing.
