It seems idealistic, but a service like this would be incredibly insightful. I only "read" (read: skim) the TOS of a select few companies (Apple, for one), so the high-level summaries shown on this landing page are immensely valuable (though the scoring system seems obtuse). Of course, now one has to worry about the objectivity of the summarizers.
Yes, trust is one problem. I think we're being objective (at least we are trying, with building a scoring system that's automatic). But for sure, we are not being neutral. We do think that tracking should always be opt-in, not opt-out.
At least, we're working in total transparency and it's an open process. I hope that helps.
Re: neutrality, I'm delighted to see that your perspectives align with mine. Dubious legal terms deserve to be called out. And the transparency is nice, but... well, if I'm too lazy to read a 50-page legal document, I hope I don't have to sift through a 50-page mailing list thread just to establish confidence in the summary of the document itself. :)
