I think this article is kinda misleading, yes you might get identified based on an ad blocker. But if you don't have an ad blocker you WILL be identified, immediately.
P.S. I did get a good laugh out of all the comments of people who are worried about being tracked online and the lengths they're willing to try not to be tracked... And still not doing everything necessary not to be tracked. I've given up at this point. The Web is basically unusable if you actually make yourself untraceable and doing so is an enormous pain.
