Although that just leaves us with the question about who is considered the owner. I’m a renter, so would that be me, or my landlord?

Fun fact: In German, this boils down to which translation of “owner” is used. I’m the “Besitzer” of my apartment (I possess it), but not the “Eigentümer” (I cannot sell it).

Deleting accounts doesn’t mean the company deletes your data. Even under GDPR (Everyone else is completely SOL here, I believe), they can keep if it is required for their business, unless you explicitly demand a full deletion.
