We’re told that “content blocker” is just a euphemism for “ad blocker”, but it is not.
Consider Board Game Geek. I visited that site today with my content blocker active. I saw ads. I clicked on two of them, and there’s a chance I end up spending money on what one or both of them led me to.
The ads that my content blocker blocks? Ads I would have ignored. Ads that are so annoying they may have keep me from even bothering to read the content of the site they are supposedly supporting.
And, my content blocker blocks annoying content that isn’t ads.
