Even if it is damaged or broken, you’d be able to return it for the full price, because you did not get what you were promised (at least in countries with legal warranty)

You pay for something once you know what you’re getting. If you don’t know what you’re getting, it can hardly be argued there was ever a meeting of minds. See the “The Peerless” case.

Sure, it’d be a solution for five minutes until someone delids the secure enclave on the gaming card, extracts the keys, and builds their own open source hw alternative.

High-performance FPGAs are actually relatively cheap if you take apart broken elgato/bmd capture cards, just a pain in the butt to reball and solder them. But possibly the cheapest way to be able to emulate any chip you could want.
