That is true. A lot of what makes smart phones invasive is built into the structures and networks; to interface with that system necessitates giving up privacy. The end user can mitigate it, but so long as the network exists in it's present form, it will always be a partial mitigation with diminishing returns the more you try.

I think it's also true that we should have these conversations about what could be. Especially with computers. These machines can be configured in practically endless ways, so it's pretty damn frustrating to see the scope of what is actually done with them get narrower and narrower.
