I really share your concerns and take your side, but one could also ask what harm is being done here, other than messing with the stats by letting code perform an action a human could do. Something along these lines: We're not asking to get these clickable ads, so if they're sent to us, we might as well just have a script click them. It's doubtful if this is really click fraud, since we're in no contract relationship to the ad platform, unlike the one who uses the platform. Click fraud could be defined as commercially interested parties generating false clicks for profit, either the ad platform or the competition creating these clicks to charge for clicks which never happened or the clients for whichever reason. But from my point of view I'd rather not do any of this as a tracker blocker, you never know if then a capable lawyer meets a bad judge and suddenly uBlock Origin will be (absurdly) ruled as an illegal piece of software.
