- Overuse of tracking, including nefarious attempts to de-anonymise users through excessive fingerprinting
- Crappy, distracting, in-your-face ads
- Ad networks serving malware (rare, obv)
If ad networks focussed on ridding the world of these issues, more people would be happy to let the ads through and help support content creators through ads.
All adds are subconscious manipulation.
I hate them, no matter if they track me or are in-your-face. I will always use an ad-blocker, but allow ads if a site asks me to do so, and I enjoy the content.
But I realize I'm probably in a minority here. Most users would not bother with adblockers if ads would not degrade the web experience so much.
So why when my maximum benefit is blocking ads AND viewing content should I change my behavior.
Blocking ads has been a thing for 17 years and will probably be a thing for the next 17.
If you could force me to watch your ads you wouldn't have to ask
This means that advertising inherently is not something you "opt into" when you visit a page. You are being tracked everywhere you go.
That's the problem brave solves, but it accepts that removing ads without another system to reward content creators is important - hence BAT.
