Why is there even a permanent ban option on classic servers

Although I sympathise with those unfortunate enough to have to keep re-upgrading to gold, if it wasn't for lifetime Classic accounts there'd be a hell of a lot less reason to upgrade for those that do.
Yet Graal's management still have this myopic belief that every single player should be paying, and that it is outright wrong to be able to properly experience the game for free.
