He's spoken out since and said he thinks homophobia is acceptable (in 2014). He's never said he was wrong - he doubled down on it saying people weren't being inclusive of people who hold homophobic views.

Ask yourself if you'd be angry if he spent money campaigning on giving, say, black people fewer rights. I'd imagine you'd be pissed off about that. So what's the difference? Why are you accepting of this?

It's particularly bad that he sells his product as being respectful of people's privacy, yet he wants the state to intervene in people's private lives and prevent them from having equal rights.

By all means, use Brave. I don't care. Use their crypto, use their affiliate links they inject into your browser, whatever. I just personally refuse to support someone who is unrepentantly homophobic.
