I mean, that's just false when it comes to 5e. The paladin can be forced to become an oathbreaker, which gives different abilities, so the paladin has some powers removed from him. The DM hands out XP, so not handing the PC any XP denies advancement. And of course, the DMG says several times that the DM does not serve the rules, the rules serve the DM, so he can ignore the rules and create his own when he needs to, and that includes removing/denial/alteration of PC abilities.It's not in the rules. The same goes for clerics, paladins, etc. There are no rules in 5e for removing PC powers or denying them advancement.
So yes it is in the rules.
