After Google Street View and their admitted storage of data from all those WiFi networks, people are very suspicious of Google with respect to personal privacy.
So much, in fact that this article outs Google's perceived intentions before the facts are known.
The potential for these microdrones is enormous:
Intelligence (police, government, industrial)
Battlefront fire and maneuver
And on and on.
Is there any wonder that Google has been associated with this technology?
There's an old saw: Just because you're paranoid doesn't mean somebody isn't watching you. But remember, Eric Schmidt was an advisor and substantial contributor to the Obama campaign, and still is an advisor to his administration.
This thread could be interesting.
