Products that oppose monopolies are important, such as Google's Android phone operating system, alternative web browsers like Firefox and Chrome, and the Linux OS. It's never a good situation for consumers when one company holds a monopoly - actual or just practical - over platforms and distribution channels. That's why Apple and Linux are important for computer operating systems and it's why iTunes and Facebook are such problems. It's not that they are bad, as such, just that they have no external point of reference.

PPS - Without that opposition, products and services grow stale and evil.
