Since this submission relates to blocking ads and trackers, I think it's worth bringing up that uBlock Origin [0] is better than Adblock Plus in (all?) ways (see the README for more details). I migrated to it a few years ago and overall I've been very happy with the outcome.
I'm opposed to all tracking that isn't opt-in by default. I haven't thought about the topic at great lengths, so there may be cases which I'm failing to consider, but I've generally found "opt-out by default" to be highly hostile to users. e.g. In the US you're only allowed to digitally opt-out of credit card prescreening [1] for five years unless you're willing to mail something out. This considerably raises the burden on the user, even though I'd conjecture most people are not interested in receiving this kind of mail, and they'd largely consider it spam. I make a point of blacklisting any service that mails me spam, and I encourage others to do the same.
Additionally, I'm also opposed to ads because I've found they're generally against the user's best interests. Humans are more important than companies.
