The problem is that the people that got banned did not pirate the shit and paid with real money the games.
If the hardware is mine and i paid a valid license for the game, i am then entitled to play that game whatever i would like to play it. I can't get a $450 paperweight if one day they decided that those 8-in-1 multiplexers for the dock aren't supported. Or if one day a production lot of cartridges is glitched and they blacklist people at random
If they blacklisted the console, then it's ok to block online gaming (and I would 100% agree with that), but playing offline games should still be allowed.
I vote with my wallet and i don't support this shit
