Edit: Not making a judgement here, just clarifying that the extension is doing more than messing with metrics.
AdNauseum doesn't hurt advertising networks, it hurts publishers. When they get banned for click fraud, the network keeps the money.
Also, increased click fraud on tracking ads lowers their attractiveness, nudging ad revenue toward sites that serve display ads targeted to their content.
This helps funnel money to sites that produce high quality content and away from low quality sites that happen to attract users that view high quality content elsewhere.
They become the publisher. In the grand scheme, this is a misguided effort that will further monopolize publishing.
If there's someone who makes content you like to see, why don't you mind draining their wallet?
Why support the middle man who just makes the Internet a worse place when you can directly support an author's efforts?
The advertisement business model just exists to justify the existence of low quality content.
Okay, when was the last time you watched one?
You want to stand by that argument, or admit that you're talking out your butt?
