No one is forcing you to use youtube. I think the situation is more like the opposite, adblockers are trying to gain control of youtube servers in order to obtain the product without paying.
Adblockers run within the browser's space, they don't intrude into any servers by any means whatsoever. Your statement is completely wrong and misguided.
The current implementation sends YouTube false information about whether the ad was run. That absolutely intrudes on the server. Really it's no different from telling a cashier you already paid online or something like that.
I guess we're even then, since they do not respect DNT.
[Edit] can't reply to below, but since I am not violating any law, I don't see how I need to admit to anything. I'll admit to using my user agent as intended.
