You're right. The issue indeed is that these companies can just vacuum up all of this data and keep it around. The problem, however, is that this is possible now. This means that if people (or companies) somehow figure out a way to either keep this information from the state or keep this information from being collected, then the state themselves could start collecting (some of) this information. We've seen it before that intelligence agencies don't seem to care about spying on their own citizens through technicalities and then abusing that information.
