If it worried me particularly I'd simply not have a Google device. If a distrust in a G+ account was enough to put me off then letting their code handle my phone and tablet in general would be a no-no for me too.

I'm under no illusions that there is much I can do to stop Google tracking me, occasionally pushing stuff at me addverts and so forth), and trying to "lock me in" where possible, as I use my stock Android devices. I'm sure both MS and Apple either d the same sort of thing or will as soon as opportunity presents itself.

I'm not saying it is right of course, just that if it is a particular problem for you then it should inform your decisions before buying a device. Also I suspect buying and returning devices as a form of protest is not seen the same on relevant internal reports, and is likely to inconvenience your retailer more than the manufacturer, so if you wish to protest the behaviour you will find simply not buying to be more effective.
