ABP is not a one-man show, it's now developed by a company (Eyeo GmbH) that makes a lot of money getting companies like Google to buy into their "acceptable ads" scheme.
ABP also considers ads that track people (such as Google's) to be acceptable and whitelists them by default.
If you make a modern-looking long-scrolling article that has an ad somewhere in the middle, it's not "acceptable". If you get a crappy CMS that splits every article into 9 pages with an ad at top and bottom, then it is.
The main weird thing is that 3rd-party tracking is "acceptable" (!)
