Do they get some kind of real-time feed that tells them "hey this URL popped up in the web today, but it is a tracker, so block it", or is this exercise is mostly helped by the crowd ?

The problem with this approach is that the companies will just change the way ads are shown. DNS blocking is impossible to stop, provides you block every ad website.

    DNS blocking is easy to stop, you just host the ads on the same domain instead of putting them on a subdomain. There are plenty of ways to do this already. Only reason it works right now is that lots of them have their own separate ad domain that they host from.

    I hate Amazon for this, and won’t use their apps or pages if I can avoid it (including the amazingly brief foray into the Amazon App Store years ago which only served ads from Amazon domains)

    Because so much of the world runs off Amazon I really can’t block that domain effectively without breaking large portions of the internet. Tho now that I’m not using Amazon actively for anything, the broken-ness might be fine. Guess we’ll find out!
