It's true that ADSB digital transponder data is open source.
It's true that a mil a/c can turn it off or even spoof some of the data.
I'm a planefag and out of respect for our President I am refraining from trying track or monitor his plane.
There's a code of conduct among planefags that apparently some newfags don't know or don't honor.
We don't report positions of military planes on missions either, if there's any chance our reporting might endanger lives or the mission. We'll save it and report later, after the plane is on its way home.
A word to the wise.
