I'm not so sure. 1. The authors of the extension clearly intend to harm the ad industry. There's no expectation that anyone will look at any one fake ad click and say, "oh, that person's sick of ads... maybe we should change our strategy." There's no business-side interaction with fake clicks like there is with empty returned prepaid envelopes. The only impact anyone intends or expects from this extension is financial. The intent is to get advertisers to pay more for fewer sales. 2. This is automated, and by distributing an extension, automated on a (potentially) mass scale. I hate ads and I'm the kind of person who would use that extension if I weren't already happy with ublock origin, regardless of whether it might be considered fraud. However, I think there's at least a passable argument that it could be. If the main reason for this removal is that Google views the extension as fraud, then banning the extension from the Chrome web store is fairly decent of Google compared to suing the developers.
