"Your ad here" is one thing, but "your ad in this person's life (which we track for you and report back)" is another thing. The ad space seller arranges a stealthy introduction between ad space buyer and Dave user. Without needing permission because Dave "agreed when he started using our free service, that we could change the terms at any time, do stuff in the background to keep the business running etc" a silent on-going relationship is established without Dave being reminded of that persistent connection. We now have default permission granted to contact list and personal details when installing some apps. I hope the rumored Android 4.3 selective permissions control per app is true. What a great day for privacy that will be when we can stop apps bullying their way into our [contact list + internet access] when that isn't needed for the app to work. The marketing-programming that is entering apps, whereby an impolite, unchecked persistent tracking, ad placement, additional purchase persuasion spamming and infiltration of our private data is happening, you don't need a tin foil hat to justify a few concerns.
