Marco Arment, talking about the ethical dilemma of using ad blockers:
I recently started using Ghostery on my computers, and a simple homemade iOS content blocker that I may release for iOS 9’s launch. The web performance improvements with these are staggering, and the reports of quite how much Ghostery is blocking on most pages is shocking and disgusting.
I struggle with the similar ethical quandary. I have been using Ghostery for a while as well, and I’ve decided to allow Google, the Deck and a few other Ad publishers through. I want to support sites if they have chosen an ad-supported model as long as they do it in a moderately tasteful way. But to me, web tracking and retargeting is a bridge too far.
What’s great about Ghostery is that it allows you to choose to either block all 3rd party trackers/ads or specific ones, and you can even choose to do so one a per-site basis. This lets me show ads from certain networks I know of and ‘trust’ on some level, while blocking all of the shadier services. It’s a simple add on for Chrome, Safari or Firefox and it dramatically decreases the load time on most web pages, and gives you some level of peace of mind.
As others have pointed out, trackers and ads nowadays aren’t just something you can simply ignore. It’s code, executed on your machine and dramatically slows down the load time of an average web site by a few seconds most of the time. This has costs in terms of time, bandwidth, privacy and even on an ethical level.
I’ll keep tweaking my Ghostery settings to let some types of ads through, but undecipherable tracker names with no obvious benefit … you’re on notice.
