The content producers who distributed their videos on YouTube agreed to Google's monetization terms. They did not agree to Brave's. I cannot unilaterally make copies of Harry Potter books, sell them for a dollar, and give a cut (even a 50% cut to make the Brave analogy complete — they like to say they give a larger cut to publishers without mentioning that it is a larger cut of a much smaller pie) to JK Rowling. Even Brave eventually understood why this was wrong.
