Alternatively, they can also refuse to serve you their content unless you turn off your ad blocker. Which would be fine. It is their content they're hosting after all.

And it's also fine for you to decide not to turn off your ad blocker and not view their content.

There are some that do this and I also think it is fair. I just close the website and do not view the content. Nobody is forced to either serve or be served so I do not see what is the problem to be discussed here.

I wonder why not many websites do this """adblocking freeloaders""" is such a big issue?
