Is adblock stealing? Do you use adblock? Why? Sure, advertisers don't have the right to your attention, but don't the content creators have the right to your financial support?
Pi-hole, Google search filter, uBlock, ... all of that let me free from ads (not at all). Ad is a problem because it make us like sheeps. Ethical ad is a non sense to me. In France, a lot of new internet newspapers works without advertising (subcriptions only). I think the problem is not ad but services without charge. I know a lot of people can't pay but it's part of the problem
I get those sour messages asking me to disable my ad blocker now and then. I leave such sites right away. I don't agree with their model of business.
