If your neighbors are traveling by personal aircraft then it is very much the same thing. There are a lot of privately owned GA aircraft and many of us don't particularly like everyone snooping on us.

Many in this community get awfully nervous about things like police surveillance of cars, license plate tracking, etc. The Police say they need it just for special cases like crime, but we all know the dangers of dragnet surveillance. This is also dragnet surveillance; it's the same violation of privacy if the mode of transportation is different. Many on this forum think it's fun though because the mechanism is a bit nerdy and they aren't the ones being surveilled.
