Since I can remember (and that's a long time), computer systems have always logged every keystroke for a couple of reasons. First it was for accountability, then to be able to restore functions then we discovered the marketing treasure trove hidden within the data collected. It fueled whole industries like junk mail and telemarketing. Using the info gleaned to target specific demographics is not new. Heck we did this back in 83-84 with credit card data no less.

So to sit back now and think that you can have any form of privacy in today's digital world is a ridiculous notion and just needs to stop. Apple since iTunes can tell potential musicians exactly how many of it's subscribers will be interested in their specific style or type of music. That's just music, not to mention each internet search, online purchase or interface with your local library. All of which is captured and re-purposed. That's the way it is, that train has left the station.
