The mechanism in place here is that the domain provides code that sites use to will block content if the visitor is using an ad blocker. The argument being made is that by preventing this code from running by blocking the domain, the site thinks you should have access when in reality, they don't want to serve the content up to you. As for your TV comparison, the better comparison is probably with satellite TVs, where you are just decoding signals being sent to you anyways, and if they don't want you watching those signals, they shouldn't send them to you. It's not the same, but it's far closer than your comparison. Note, I'm not backing either side with this post. Only explaining the argument so you have a clear understanding of the issue at hand. Whether you agree with it or not is immaterial, but understanding the rational is important.
