I don't see how this is true.

There is nothing about PaaS that says there can't be compatible competitors. Hell, there have been PHP shared hosting platforms that were very nearly identical between providers for a decade before anyone started saying PaaS, and really, the "Innovation" that made shared hosting PaaS lies in per-usage billing.
