But unless I misunderstood things, the software merely does a check if the hardware looks sane, and if not it displays a message saying that this is the wrong hardware, and it refuses to continue running.
You do misunderstand the situation. Elnec has publicly stated that it checks for one of the illegal clones and subsequently erases the NVRAM. This is independent of the owner's knowledge or lack thereof, that he's got a bootleg copy.
The intent is clear, as is the public statement. They're taking a gripe they have with some Chinese bootleggers and depriving (stealing) the use of your device because it isn't theirs. That is, they've determined that the device isn't legitimate and, as a result, disabled it--in lieu of taking action against a hard-to-pin-down bootlegger.
And, as mentioned, FTDI tried the same approach and got burned badly. All one needs is a hungry lawyer--class-action cases can pay off big.
