I click on the ads of products I dislike so that the company gets charged for the ad. If you wanted to inflict the maximum damage, then click on the ad and install the app. Uninstall it later. I think the ad gets charged more as a "conversion".
I'm not in deep enough to tell you whether that's a net loss or benefit, but it's probably close enough to zero...
But you're always going to see an ad regardless, right? If that's the case I don't see any advantage in making yourself more expensive.
Your impact on any other keyword would be effectively zero.
You would be better off spending the 5 minutes you wasted on something positive.
