Some of Google's user-hostile decision making is backed by marketshare data. "This is what users really want, they trust us," Google says pointing to how massive Blink marketshare is. That is a cudgel they use in the standards processes and in disagreements with Apple and Mozilla that they have the most users. Brave contributes to those user counts and Google's outsized voice in the market and in the standards processes. It's great that Brave tries its best to turn off the worst things Google is doing in their fork/patchset, but they are still complicit in Google doing some of that in the first place by contributing to the marketshare of "Google's browser".
