Earlier quoted context omitted.
"I am this browser, requesting this content on behalf of the user, who clicked on this ad." Walk me through this, okay?
I don't understand what you're asking for.
(1) a false statement of a material fact
The extension is telling the site, "I am this browser (user agent), requesting this content (what's behind this ad url), who clicked on this ad (calling the onClick handler of the element that has the ad."
That's not true. The user did not click on the ad.
(2) knowledge on the part of the defendant that the statement is untrue
The user knows they did not click on the ad.
(3) intent on the part of the defendant to deceive the alleged victim
Everyone in this thread is saying it's to confuse the metrics, and some are saying it's to purposefully take money from the advertisers.
(4) justifiable reliance by the alleged victim on the statement
The vast majority of HTTP GETs to URLs that are only found as href on Ads are requested because the user clicked on the Ad in their browser. Can you name even ONE other time a browser follows the onClick event on an Ad?
(5) injury to the alleged victim as a result.
Money.
So, walk me through how this is not fraud?
