In the past few years I've been working a lot on Bitcoin, so I've become quite familiar with how the banking world works and what they collect and track about you.
If you really think Google and Facebook "track users relentlessly and insatiably" then I suggest you take a deep breath, and then go review what banks do in the name of anti-money laundering. It makes social networks look like quasi anarchist chaos camps. I mean, you can tell Google and Facebook your name is literally anything - they aren't going to check. They barely even care beyond trying to nudge you away from picking pinkponies_78, so the search function works. Google isn't going to suddenly suspend your email account and demand you provide documentary proof of where your business is getting its income.
WRT this: Google omits basic facts in their privacy policy about the data they collect about you
I don't think they do:
http://www.google.com/policies/privacy/
Just go read that page and it covers a huge number of topics including things like "who sees your data inside the company". I'm sure you would want even more info, but these sites represent a trade off - earlier privacy policies were dinged (by governments, lol) for being too large and complex.
