I didn't read it as cloud applications should be interoperable between providers but that a given application should be able to pick which platform they build on. I've had a similar argument with a previous employer who wanted to select just one provider. I was baffled at the time as provisioning an account on any of them takes seconds. So there's no reason to pick one other than politi---and right about then is when I understood the whole motivation.
