I'll give you a recent example: there's nothing wrong with servers running ad-block detectors and not serving content to people running ad-blockers. It's within their rights. It's not "within their rights" for people to circumvent these and try to see the content anyway.
Since on a technical level the content owner's web server is both serving the content to you at their expense, for which your browser makes a request, and also is specifically serving copyrighted content, and finally on a moral level has created that content at their expense, I consider it absolutely, 100% within their moral, legal, technical, and decent rights to throw up a TOS saying: "Our business model is showing you advertising, and you agree to load and not block ads. Click 'I agree' to proceed". It's in my opinion within their moral, ethical, technical, and legal rights to detect and block people using ad blockers. It's not a technical "arms race" for people installing plugins that let them trick the server into serving them content even though they're not displaying ads, while the server chooses not to display them content. Even if there is NO such click-through TOS being thrown up, the server by running ad-detection algorithms makes this relationship abundantly clear.

All of my contributions were downvoted, which is fine, but people were also extremely rude. They didn't understand my bakery analogy, and focused on something irrelevant, the TOS. (This is like saying the bakery didn't have a sign up saying you couldn't reach behind the counter and take something. I mean, the fact that the server is actively running ad-block detection and wanting not to serve you isn't enough? It's also irrelevant because it takes one line to add that to a TOS so it's not a real response.)
So here is an example of a fine contribution in which my view is correct and HN groupthink is completely wrong.
untog pointed out that my comment was correct by stating "Seems telling that you're getting downvotes but no replies explaining how your comparison is wrong..."
Going forward, of course I will not be using that analogy.. Indeed I won't post on any ad-block related subjects.
Of course, this doesn't mean I don't expect people not to run ad-blockers, just as the existence of copyright doesn't mean I don't expect people to torrent stuff. I just mean that they're not morally in the right, they shouldn't act righteous about it, and servers that refuse to serve people content when those people are running ad blockers are in no way (not even a tiny way) in the wrong.
I'll probably be downvoted for this, I just wanted to give you an example of something that I wouldn't post. I literally wouldn't be posting this now except as an example of something people will downvote.
