People want a browser with an ad-blocker, and are too lazy to configure it themselves. Brave adds it and starts some "tell your friends" marketing hype. The rest writes itself.

It's always shocked me, but this really is the case.
I make a habit to install an adblocker (if they consent) whenever using a friend's computer, and have had many thank me for doing so a week later, saying what a huge difference it is - but none had thought it was worth the "effort" before.
