Lots of strong emotions here, as usual with anything ad related on HN. The fact is that advertising pays for much of the internet content you consume for free.
Yes, it's not ideal and the online implementation is poorly done most of the time. It's because of perverse incentives and a lack of regulation in the entire industry that force bad formats, fraudsters, malware, and the pursuit of data and volume to win over quality and user experience.
As much as I don't care for the ABP approach, it's something that can be used to actually make progress and that's what this is, progress. It's finally some outside pressure on the industry to change from the segment of the advertising mechanism that matters most - the people themselves.
