There are many good reasons to use adblock and anti tracking software for your browser. Ads and tracking sites are annoying, potentially dangerous, they slow down your browser and they hog your bandwidth. All very good reason to simply block ads no matter how much a youtuber or website is whining about lost ad revenues. Within these bounds the user is perfectly in his or her right to choose to use this software.
But there is another good reason to block ads. A reason that could actually make NOT using adblock a bad thing to do.
