Generally not knowing and not having the mind for that shit is ok, as long as you pay somebody to do your business. Well he used to pay radium for that, even past the point where it was obvious that radium doesn't do shit. He still put up with radium though because Lowtax always loved being surrounded by yes-men, even if they were useless. Every time you tried to call him out on things on the technical side not fucking happening because of radium you just got this very passive aggressive ironic-detachment-to-the-nth-degree "lol yeah I'm bad at internet business. Lol you care about it lololol". Then, in typical Lowtaxian fashion, he dragged radium through the dirt publicly when he "broke up" with him and played the victim. Justified or not, it's not professional or even decent considering he saw radium as friend once. Then ZDR sucked up to him enough and we know the rest.
Shit like this is why I don't feel sorry for Lowtax at all and find it kinda amusing that it all goes to shit for him.
