Playing your ads in my browser is "the rules" now?
If you want to claim it's "the rules", you need a paywall.
Oh, you're not putting up a paywall? Fancy that.
Do you offer legally enforceable indemnity against people getting malware from ads you serve? If not, then you can't really tell them not to block the ads.
"The rules" in this case are that censorship and social control (presumably) exist on the platform. If you don't like that, don't participate.
But don't say, "OMG censorship" and use that to justify defrauding advertisers while continuing to use the free site that you deride.
It still doesn't justify the topic at hand, which is a program that attacks the ad networks and defrauds the advertisers.
You can protest legally by blocking ads, but there's such a thing as too much civil disobedience. Its a slippery slope, because this argument can be used to justify DDoS.
