Yes I agree. If you are using adblocker you are already not an average user. Using A adblocker with custom filters put you on the extreme end and most of those users are either already on FF or have migrated to FF since the MV3 announcement.
And let's not forget adblock made for MV3 will work well enough for those users who aren't using adblocker with custom filters.
Even if Google kill off adblock completely with its browser, chrome will still be dominating the market by a huge margin.
What is there to recognize? This is a survey conducted on 2,000 Americans. 2,000 is just 0.00057% of the whole US population which is estimated at 345,426,571.
The average user absolutely do not use block ads unless it is enabled by default in the browser. Chrome with the largest market share does not block ads by default and if you are going out of your way to block ads or use a browser like brave that do that by default you my friend are already not an average user.
