Nikola Tesla and Thomas Edison could have both had kids in their basement, would that stop me from using electricity absolutely fucking not, someone invents something I like, and is useful to me, I use it, I don't fucking care what he thinks about anything, he could be best mates with fucking Kanye and make music about how he fucked his cousin, I'd still use it, it's open source and useful, he works on it full time from what it seems and maintains it for himself and not you lot and your huge fucking egos who think everything revolves around you. He wanted to make something he'd find useful and decided to share it with the world.
Would you stop using anything mass manufactured, just because Henry Ford, who did in fact have actual Nazi ideals, hated Jews and worker's rights, invented the conveyor belt, and call anybody that uses mass manufactured items a fascist?
