It's not black and white or simple as you think. Since he started creating games, icstor's earnings peaked only after he stopped updating. before that, even though he made regular albiet rushed updates, he was earning lesser with the period of caroline update being the exception.
also, the amount of money he's been earning is more than good enough to support him for the foreseeable future. also regarding his name getting tarnished, If he started a new patreon page under a different name, how would you know it's the same person?
He already earns more than enough to hire an entire team to do his work while he sits back and relaxes. but he doesn't need to because he has 6000+ blind foolowers that already give him more money than he'd be making if he hired people.
