Good point. Nostr doesnt solve this yet, but it is something cryptography folks been thinking about for decades, so hope someone will solve it. Ie rotating keys.

Will Nostr put people back in control of their data?

Well I'm not too sure, more control rather than own, if you lose your private key or it becomes compromised, then your "identity" goes along with it, which could be a big problem, imagine that person now has all your followers, content and could swap out their LN wallet and make money off the reputation that you built
