I've started reading "privacy agreement" for Google's "do not track me" browser extension the other day and it just seemed grotesque.
It's impossible to know everything that they've actually done with your data, so I don't see how you can maintain that they've been responsible with it.
One arm of Google might be doing good things, but another arm might do bad things, like optimize engagement, ad clicking, manipulating buying behavior and stuff like that, or even worse.

a) The law states they cannot do this arbitrarily and most of us may not want them to do the 'free for rall'.
b) I doubt that the 'free for all' produces many benefits beyond targeted ads.
Seriously curious, what 'cool stuff' does Google do today that fundamentally relies on this 'free for all'?
Traffic information is probably one nice thing that requires the sharing of data. We could totally narrow the kinds of information shared, and on what basis, quite a lot with that one.
What else?
I hope they continue doing more cool stuff and measures like these don't end up limiting any future developments.
If anything I just wish I could more easily see what internal data all the advertising companies have on me. I'm sure they know more about me than I know about myself.
