is there anything that can be done about brave browser
 

Brave is a free and open-source web browser developed by Brave Software, Inc. based on the Chromium web browser. Brave is a privacy-focused browser, which automatically blocks online advertisements and website trackers in its default settings.

Do not matter their market share is insignificant.

This. Their browser market share is below 1%.

I use it on mobile, it's great :)

It's essentially a permanent version of Chrome with incognito mode enabled.

Anyone using Brave is dumb.

Lol why ?

ad block traffic, vpn traffic, and proxy traffic, are all affecting your revenue much more than brave browser ever will.
