Why Are Game-Key Cards So Controversial?

[Helloplite]

I frankly don't understand the furore. Most games these days don't ship with the full playable game or need a major day one patch. If game preservation is the reason, why isn't there an equally large move against Steam and most video game updates? I have Cyberpunk day one on disc - so what? The game is completely unplayable in that state. Game key codes at least are transferable and I don't see how they would stop being supported within 25 years. For the record, I have 3DO and Saturn games that have already rotted rendering my physical media unplayable. I have Amiga originals on floppy discs that have also demagnetised. Hell, my Game Gear is no longer working because of degrading internal parts and requires cap replacement. I think these game key cards are a decent move to improve digital content delivery and don't deserve such outcry.
