Earlier quoted context omitted.
90% of the whitelist is not paid, and that 10% helps develop the program. Not only that, you are asked upon installation whether or not to allow for acceptable ads (which is ticked on by default, but still not such a controversial point as you make it sound).
90% by lines or sites or 90% by money? ABP charges medium-sized websites through the nose -- and most startups qualify as medium-sized. Great business model, especially given that the filter lists are made by volunteers.
Except, the acceptable ads list for larger companies can only be modified by Eyeo, and they only do it after being paid. It’s a racket.
