You’re leaving out some key factors to think about: they aren’t going to take responsibility for problems caused by mistreatment while the thieves are moving it around (heat or vibration can take time to manifest), or the possibility of something being modified before the buyer gets it. A common scam in many industries is someone taking legitimate packaging and using it to sell counterfeit or returned/failed products at full price.

This is EVGA saying they don’t want their reputation and finances on the line for any of those things which can happen outside of their control, which seems reasonable.

More importantly, they’re also sending a message to potential thieves that this is not a good thing to repeat. Publicly warning buyers and preventing those cards from being treated as equally valuable as the legitimate ones threatens the profitability of stealing them. Given the high prices in the market currently, that seems like a good message.
