I can see two cases for ethical ad-blocking
1. When it prevents me from accessing the content in the first place. Have you tried accessing el-reg over a slow link (f.e. a couple of channels of Edge in the sticks) from abroad and using an under-powered machine. You will tolerate it without an ad-blocker for ~ 1 minute. After that you will reach for the technical solution to kill the X HP and Y Intel flash pieces of garbage on the page (where X+Y > 5).
2. When the admen have crossed the line between humans and scum onto the scum side. That is pretty much any syndicated targeted ads nowdays.
The industry is doing it to themselves forgetting the lesson of the early Google. Google early on bulldozed all the other ad brokers out of the way by having unobtrusive useful and non-resource hungry ads. We will tolerate that. Any day.
Shouty intrusive crap like the one DoubleClick (it no longer deserves to be called Google) serves today based on digging through our dirty laundry basket (with or without IoT help) - nope, not so much.
Biting the hand that feeds IT
