>YouTube is free to make windows and Mac apps, and turn off their web views.

I have revanced which edits their binary to remove ads. I don't see what your point has to do with mine though. My point is this: adblock users are grazing from youtube's field. We are eating the grass that youtube has planted and watered. To expect that such a field exists and then to expect that it can be eaten from at will is entitlement. To say "but they put up no fence" (or, more accurately, a weak fence) is not a refutation of this point. In fact it is exactlty what defines it as being a tragedy of the commons.

They're also free to build more serious adblock countermeasures into their website, which is exactly what they're doing now, and people are complaining about it.

As GP said, maybe this is not your position, but it's a common enough one that their comment is not out of line (given that you are the one who replied to them).
