But are really this many users actively using ad blockers? Presumably, a lot of users are on mobile devices where they are using the native app that doesn't even support this. If we subtract them, then a significant share of users on browser would have to be using EasyList.
I don't hold it against anyone. YouTube's ads are horrible, and overstuffed into videos.
I use premium and know not everyone can afford it, but one concern I have is premium views are also not counted if someone still uses the adblocker while logged into YouTube premium. (So you miss out on the view and on that extra bit of premium revenue).
