Except it’s not bullshit. EasyList does exactly what they promise: privacy.
Prefetching is always privacy issue because you don’t know what’s running on the server side. They will log what I’m looking at and which sites I’m probable to view next. That’s almost Amazon level on page tracking.
I think I could probably build an invisible grid and use that script to track users more precisely, but I haven’t looked into it.
Prefetching can be misused and therefore should not be allowed. And yes, it’s theoretical. So are XSS, CSRF, and others.
