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.
