> I don't think you can reasonably frame clicking on too many ads as an act of sabotage. It's interfering with the metrics that some people who you don't necessarily have a business relationship use to make business decisions (like paying out money), but it's not obvious to me how you're obligated to be particularly cooperative in their gathering of the metrics. The system continues to work as intended, you're just not supplying it with the data its creators would ideally hope to receive. That also seems to contrast it with a DoS attack.
Blocking an ad/tracker is being "not particularly cooperative", and fulfils the goal of not seeing ads or being tracked pretty well. The entire point of modifying an existing ad blocker to click everything, as stated by the creators is to disrupt the metrics to the point where the system doesn't continue to work as intended, and cost the indiscriminately clicked ad-purchasers an average of $1.58 per wasted PPC click, as they've taken the effort to estimate (see their FAQ).
I can't see how anyone can honestly argue that a tool whose creators openly state that its purpose is to indiscriminately "obstruct" and "resist" an industry to force it to change its business model by rendering its analytics worthless and wasting PPCers budgets isn't sabotage, irrespective of whether they agree with the desirability of the end goal.
