DNT is a bad idea that does nothing useful. Discouraging people from using it is good, just like IE always sending DNT is absurd.

Android permissions aren't great. When Android was being designed (before Google bought it), the permissions were a huge step forward from desktop apps, which can still do anything at all. Arguably the very concept of upfront permissions is inferior to asking when needed, but attributing malice to the choice is silly. It'd also be really hard (or even impossible) to change without breaking all the apps out there.

G+ is annoying, indeed. They were aping Facebook with the real names thing and they should've known better.
