Why don’t more people use ad-blocking software?
The following is my answer to the question “Why don’t more people use Adblock Plus or other ad-blocking software?” on Quora
I think there’s one main reason: They don’t know such software exists.
And even if they do, it’s not a one-click install-and-forget procedure. Once you’ve installed it, you have to deal with false positives and things not working 100% right. Occasionally, content gets blocked, or JavaScript stops functioning. I install ad blockers on all my browsers, but there are always sites I need to whitelist. For that reason, I never recommend ad blockers to my non-techie friends & relatives.
