But where do you draw the line? Not buying a game that was created by the Nazi party to promote antisemitism is one thing. Shunning a text editor because one of its creators once said something you disagreed with politically, is another.
Capitalism is about choice. If my local greengrocer is rude to me, I can choose to take my business elsewhere.
If the author of a text editor doesn't share my sentiments on whether to ban tobacco adverts, I can choose not to use their software.
People can make the choices which make them happy. I'm happy to use a slightly worse text editor if it means I am not supporting someone I don't like.
I also don't the sweat the small stuff. Hideki Kamiya has been accused of being a xenophobic ass and maybe he is, but people are entitled to their bad takes and internet drama isn't going to stop me from enjoying games he's worked on.
