They don't care. But more importantly, courts won't care. Your compute is all tainted and has the wrong colour, due to your intent of working around the licensing restrictions.

you couldn't do that. Because you're deploying the GPUs for other purposes besides blockchain processing 99% of the time. What you could do, is write a very trivial blockchain and Have it require a couple of ledger entries that are DL "input data/gradient". Hard to argue what exactly constitutes "processing". This way, every cycle of the software is dedicated in some way to the blockchain.
