And yet ublock origin tries to work around this. About a third of their issues are "this site refuses service to people with adblockers": https://github.com/uBlockOrigin/uAssets/issues?q=is%3Aissue+...
If these sites really don't want you there with an ad blocker, they can actually block you. I imagine they realize there is value in getting more eyeballs even without ads, whether that be that users might still recommend and create links to your content that other people without a blocker then follow, or you actually sell something and some of those people might buy it. Whatever it is, by revealed preference, those site owners seem to be indicating it's worth it to allow people to browse with an ad blocker.
By default, we do not try to work around sites which make a polite demand that the users disable their blockers without preventing access, this way the final decision is up to the users.
Nope; uBlock Origin will work around that as well. Skimming recent issues, in https://github.com/uBlockOrigin/uAssets/issues/15338 atozmath.com detects that people are running an ad blocker [1], explains what they're doing, and refuses access. The discussion is how to make the site think ads aren't blocked, though they haven't succeeded yet. In https://github.com/uBlockOrigin/uAssets/issues/13801 there's a simpler one with https://www.magicgameworld.com where it refuses access but doesn't provide reasoning, and that one was fixed.
