I think there are dozens of good reasons to criticize the AI bubble, but 'stealing IP' is the weakest one in my opinion.
Most people seem to have no problem with piracy, for example.
Heck, in the early 2000s the free culture movement and Pirate Parties were gaining steam to reform the draconian copyright laws we have.
The problem is not stealing IP. It's Big Tech getting away with laws while the rest of us are punished.
