the thing is, even if you "own" your data you still need to give it to companies to use their product. unless everyone runs software locally, in which case the majority of the populace needs to learn how to use devices rather than falling for the trashy "itjustworks™" chromebooks and convenience devices that milk them for data profits whilst appearing cheaper and better to integrate into their lives.
especially with google - you cant run services like theirs locally really, and even if you request your data, you cant ever really find out how they use it or what they have done with it. its the illusion of ownership. data isnt ownable. its simply transferable.
