I think it's a case of judging a band by its fans. Enough dodgy billionaires have jumped on to create a poor image. Singer never said donating buys you a license to be evil.
I only know about SBF but SBF was a scammer. Are we surprised that scammers try to use anything that could give them a positive image in order to, you know, scam people ?
Also I don't see Elon Musk giving out his money to save non-white people's lives anytime soon
