Brave's co-founder (and CEO) is also the co-founder of Mozilla. Our other co-founder (now CTO) was also an engineer at Mozilla for many years, and behind many of those contributions (several other Brave staff is directly connected to Mozilla as well). They started Brave in the same spirit, to improve that which is broken, and create a better, more equitable Web for all.
Thanks, that's a good point. BAT and the associated concept of rewarding content creators or Brave Search could be seen as contributions to the world as well, I think.
