I would be OK with ads that went straight to the site selling an item with no tracking other than click-thru stats but not using the IP address, not fingerprinting the browsers, etc.
It's sick that sites show one price to mobile users and another to desktop users. I've seen this by testing it myself. It's a sham. It's the seedy side of capitalism. Everyone should get the same price. Another reason to block ads, since allowing them means you're buying into the way they do business.
Nothing mean-spirited about blocking a very strong vector for malware, which we all know ad networks have become. I have a moral imperative to protect machines under my control, so we block all ads, disallow all tracking, use Disconnect, Ad Block Plus, and HTTPS Everywhere, along with other in-place tools to allow users a clean Internet experience. Let's not even mention how much bandwidth is saved by adblocking... That alone makes it worth it.
