The way I see it they're already going to get my data through their services, and they have a massive interest in keeping that data secure in order to keep trust in their brand and keep the data flowing. I oddly enough trust Google about as much as I can trust any of the big platform companies with my data. They risk a lot more than most by treating it haphazardly.

Even ignoring the data privacy, these don't support previous generations, so don't expect good support for these things if you want to mix and match models. Who knows if the next gen will support these.
