You're sort of leaving out the fact that ABP launched its own ad network and advertisers had to pay them to get listed as 'acceptable.' It torpedoed their trustworthiness in the eyes of many.
Also, ABP made the setting silently opt-out instead of asking the users. That, and their new diametrically-opposite incentive of whitelisting ads for money made me bail from them.
If at least they had made an easy to use panel to opt-in which kinds of ads you were OK with (Text ads, static images, animated images, silent videos, etc.), it would have helped their case a lot.
