Note that those techniques are in the spirit of the initial vision of the internet being open and free, and you, the user, controlling what you see on the web through your 'user agent' and not the other way around. Also remember those ads are not free, they come at great cost of bandwidth and compute, resulting in net co2 emission. If I as a user want to object to that, using an ad blocker is morally completely valid.
