Adblocker is a huge disability tool for those with disabilities, especially people with ADHD and autism. It also helps many other people who are disabled or have certain issues due to certain challenges. If you need a better explanation, you can find one here:

"Advertisements are not compatible with my disability.

I'm autistic, which means I have an invisible disability. I'm pretty good at masking, so it's even more invisible, but that means I have to spend a lot more time regenerating when I'm alone, trying to regain all the energy I spend masking in public. And this is a common experience with people with more invisible disabilities, they have to put in a ton of invisible labor just to exist in a world that is continually oppressive and exhausting. Very often we pay 'disability tax' which means we have to spend more for things than non disabled people- whether that be specific types of clothes, certain dietary items, medical treatments, or certain services. And after a while, you get tired of paying that disability tax, again and again. When people argue that people who have sensory differences should just pay extra for ad-free Yahoo, my reply is that I'm tired of having to pay extra for accessibility.

Accessibility is a right, not a paid service."
