Also there is no punitive damages in U.K. law. So what’s the worst that could happen? Would you put them back in the position they would have been had the contract not existed, so give the cards back plus a contribution towards depreciation? Would be interesting if someone with legal knowledge could chime in.

They could potentially claim damages for the difference in price between the GeForce and the equivalent Tesla, using the argument that using the GeForce in a DC has cost them that amount in lost revenue.

Of course, a counterclaim for existing owners would be that the product they purchased was licensed for DC usage at time the contract was entered into, and so the original rights cannot be unilaterally revoked without consent.
