Not business ethical. I can buy physical copies at a used book store for the same price or better. They save a ton, with little overhead by not producing physical products and then turn around and mug you. Plus I can't get the character sheet function to work at all. No option for character sheet. They don't care about the community, as there is no reply on bad reviews, no promise to do better with an update, no "I'm sorry but...", No "piss off!" No nothing.
