I like this idea, although I don't see how it would solve the problem of providers ejecting content they disagree with. All I think it would do is allow people to shield their real identities. Sites like the Daily Stormer (which I personally find disgusting) could still be shut down by a cloud provider who disagrees with the message.

What might be really interesting is a cloud service that allows anonymous accounts, and also has a free-speech-absolutist policy (and sticks to it even when it's hard).
