I do think there's an issue with companies like Facebook owning peoples' data. Instead, with Web3, the idea is that people own their own data, can verify who they are (they own their private keys), and can choose to interact with services on the web and share their data as they see fit.
I agree with you though that it's great to be able to download movies or music (even though the trend seems to be moving more and more towards streaming). I don't think Web3 means that everything is arbitrarily limited though, it means that it's more user controlled [1].
