I use an ad blocker because I hate the idea being tracked. Hiding ads is simply a plus. I like the idea behind Webpass but they do nothing to prevent the tracking part of the whole ad blocking discussion.
I'm one of the co-founders of Webpass.io, and a dislike of being tracked is the primary reason why I am inclined towards using an adblocker myself. Before I realised the amount of tracking that went on, I hadn't been motivated enough to use an adblocker.
Webpass.io has been designed with this in mind. Webpass.io involves removing the advertiser from the transaction -- partnering sites remove advertisements, which should eliminate tracking by advertisers. When it comes to trackers from other sources (e.g., analytics), you can continue to use plugins like Ghostery or the EasyPrivacy list.
Webpass.io is a way for you to support websites, that is compatible with whatever means you use to protect your privacy. You don't need to opt into ads/trackers/third party cookies for our service to work. We track little from our users (check our privacy policy), and we have plans for the future to make our privacy features even stronger by offering (near) anonymous use of our system.
As for our own website, we have avoided using any code that could be used to track you by third parties -- no social media buttons that talk back to their original servers, no third-party commenting system, no third-party analytics, and so on.
