I think the difference is consensual sharing of the information. Many would probably be OK with certain types of information collection, but the way some things are collected without overt notice or consent (Example: Wi-Fi SSID to GPS long/lat pairings on phones) is understandably concerning to some.

> If someone can devise a way for me to share my information while controlling how that information can be used later, it would go a long way to striking the right balance. I guess that's more or less "personal DRM" for our information.

It would not be easy to do this in a technical manner, as it could be defeated (as with most DRM). It sounds like a legislative solution would be best.
