I hate to be the pain in the ass who makes this pedantic point because I generally want the things being said here, but:
That IS a "cloud". 

A network of remote devices, the vast majority of which are not yours, that provide compute and data for each other or for edge devices. That's a cloud. 

The term "cloud" has unfortunately become synonymous with "centralized MEGACORP spying servers", but it could just as fairly be applied to a dark net of voluntary peer-to-peer nodes. 
My point being: let's recapture the "cloud" and celebrate it, rather than tie our hands behind our backs trying to avoid "other people's computers". Relays are other people's computers. This is good.
