It’s because making the choice of not being served ads is increasingly a technical challenge/hobby undertaking. Nerds like challenges. Other people are unaware it’s even a choice they have.
You're right, but it's not because it's a challenge that we like, it's not like this is something enjoyable. Nerds do it through gritted teeth, it's annoying to bypass all of that. They just know it's a possibility and care about it enough to pursue it. Most people don't know and don't care.
