Why Are Game-Key Cards So Controversial?

You never explained the “What difference does it make?” part. I still don’t understand in what (meaningful) sense is a GCK any different than a game with the full game on cart. You can loan the game to others, the key card will almost certainly still be fully usable well after the servers go down, etc.

If I get a regular cartridge for my Switch after the servers go down, I can still play the game. Maybe I don't get all the updates, but I still have a playable version.

If I get a game key kart for the Switch 2 after the servers go down, I have nothing but a piece of plastic.

What evidence do you have of this? Precedent shows that these companies will honor a digitally purchased copy even after servers go permanently down, so it would make sense for this practice to carry over to GKCs. Do you have any reason to reject this?
