Excellent advice. My primary concern is to avoid data leakages to marketers, app developers, and the Googles of the world. My secondary concern is to avoid being caught up in dragnet operations of the sort that the article is reporting.

Trying to evade a governmental body who is interested in me specifically isn't really on my radar at all, in part because I'm not interesting to such bodies, and in part because if that becomes a point of concern for me, then I need to stop carrying any devices that transmit radio signals at all.
