Unfortunately, “not tolerating this BS” just means “Not buying from them”, and by the time you see that it’s a problem, it’s too late for that. Even if this was a clear-cut case of them breaking some law, which it isn’t, it’s Apple; they have more money than God, and you’d never successfully sue them before they bankrupted you.
Calling this glitchless is a little misleading, unless you’re suggesting that carrying spells over from one run to the next was intended / normal functionality. This also requires a mod-constructed wand that isn’t possible to get in a non-modded game.
It’s still awesome from a theorycrafting standpoint, but there’s no one arguing that this is a legitimate speedrun.
