Readers who like a certain genre tend to read multiple books from the game genre, so these authors should be more like friends instead of competitors, which makes this betrayal harder to understand.
When it comes to creative stuff (non-essential goods), I try to only support people with good conscience.
I have cut Netflix because of what the CEO has said. I have boycotted Ubisoft and Activision games because of the continued harassment issues in the company.
There are things I want to watch or play. But if this means supporting shitty people, I would instead prefer to use those resources to support the people I like. After all, its not like there are lack of entertainment in this world.
For essential goods (supermarket chains, goods made in less developed countries with labour issues, etc.), I am less strict because…well sometimes they are impossible to avoid.
