Another disadvantage is that turning off "web and app activity" prevents useful features of Android Wear from functioning, e.g. setting reminders or receiving commute time notifications. If it weren't for smartwatches I'd still be using Android with all account activity settings turned off (or "paused"), but instead I am reluctantly using an Apple Watch (and therefore an iPhone, unfortunately) and searching with DDG. By the way, I'd happily pay for software with the ease of use and functionality of Google's location history browser if I could host it on my own server and keep all that location data to myself.
