I don't see any of this as legitimate reasons to stop using Brave.
- 
yes the CEO donated $1k some 10 years ago to anti-LGBT stuff, and that's bad, but kinda small fries in the totality of factors.
 - 
ads. Firefox has ads and trackers just like Brave. You can disable them on either.
 - 
you can also disable crypto.
 - 
hijacking affiliate codes is unethical and should be stopped but don't actually affect me in any way.
 
What else ya got?
