Unlimited is a marketing term used to express simply to the consumer there are not overall limits placed on your storage provided you adhere to the rest of the terms of service.Which specific clause of the TOS is this violating?
In the context of data cloud data stroage when Google, Amazon and the rest talk about "unlimited" they are referring to unlimited PERSONAL storage of data you create as a person, this would include backups of your personal computer, photos, important documents,etc
That's your interpretation. Nowhere do they actually claim or imply that you're only supposed to use it for data you create as a person. In fact, it'd be absurd, considering that sharing files is built into the system.

That companies lie to us repeatedly under the guise of "common sense", as if they followed the same standard when applying their unreadable TOSs against us, is bad enough.
Corporations are not your friends, and they won't hesitate to block you if you start becoming a liability. Assuming good faith is absurd, defending it publicly is grotesque.
