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 ?

Maybe a general pop-up blocker which is built into modern browsers now, but something that blocks tracking and ads (for example uBlock Origin, AdGuard Home, PiHole…) works off of a list which is kept up to date by crowdsourcing. I’ve never contributed to one of these efforts, but there are lots of people dedicated to the cause.

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.
