<i>Whether or not one thinks that Google hoovers up user data</i>
Is there any doubt about Google's hoovering practices?
<i>it is hoovered by consent</i>
Is it though? Looks to me that Google is collecting a lot of data about people that they didn't consent to. DNS queries, Google Analytics, email messages sent to other users' Gmail accounts, etc etc. And those are just a few of the more obvious ones.
