The way I see it, I don't have much direct control over the actualities of that kind of nation-state spying stuff. However:

1. I can direct my consumer-dollars towards the vendors that promise to respect ownership and privacy in general, and they will also have the most to lose if they are caught enabling spying.

2. Defense in depth. Security features generally add to the spying's difficulty, expense, or risk of detection, and that in turn decreases the incentive for abuse.
