I too am a little confused on that score. The advertisers continue to know your interests (i.e. the sites you visit) and can build a demographic picture of you based on that.

The only thing this deprives them of is your ad preferences. But given how few ads most people click on, this information is sparse regardless.

I think those devs think fhat it obfuscates data about you, data gathered about you in ad network does not match your real preferences so it is effectively useless. So it does not prevent tracking but it just cheats the system.

Don't know why they assume extension should click all links, clicking random ads would be much better strategy if you ask me, this would be less likely to be detected as it mirrors actual users behavior.

Not sure what might be the exact point. I mean while that would make useless extracting information about your add clicking habits, they would still know what webpages you visit. So it may be counterproductive compared with a normal ad blocker.

It's explained on the site. If every ad is clicked by everyone, tracking data is useless.
