I don't know. Should I care? Can you provably tell it from the data? Why authorship should have any bearing on what happens with it later?
If I shouldn’t care who made it, why should I care who stole it?
If I’m not giving money to the creators, why should I give any to the thieves?
Either pirate for free, or pay the creators.
You argued that gathering of data signals ownership of it. But I don’t know that reasonable people would agree that that’s about framing.
If you’re going to argue data ownership at all, it seems to me the creator of the data is the owner, unless transfer ownership to another person or to the public domain.
On the other hand, I can understand a stand that data can never be “owned”, but I don’t think you are saying that.
