Agreed. I used to disable it for some sites but honestly it is just not worth the effort since you never know which malware some ad network is going to serve and you need so many addons now to work around all the crap the tracking industry does that disabling it just isn't feasible any more. If the ad based financing model dies because of it then so be it. The advertising industry is meanwhile literally ruining our society, our environment, our political system, our health and many other aspects of our lives so they deserve anything they get.
