The power of a legal obligation like the GPL lies in its ability to bind equally people you like and people you don't; and in contrast to popular belief, social attitudes (like yours) do influence the courtrooms' disposition towards such laws—they certainly influence the lawmakers passing amendments and clarifications.

If we, the relevant community, do not think much of GPL violations when they hurt people we dislike, the social foundation that gives power to the law goes away.

very noble, but when your enemies are the harlem globetrotters, firm commitment to principles just makes you the washington generals

RTEMS isn't for the kind of missile you're thinking.

The kind of missile RTEMS was built for carries not bombs but science. The kind that put men on moons and get them back again.

Those are called rockets, not missiles.

And if you look at the "Applications" section on RTEMS website, the very first entry (https://www.rtems.org/applications/hardware/avenger/) says:

"The Avenger (http://www.boeing.com/history/boeing/avenger.html) is fully automated, short-range Avenger air defense system. It is a lightweight, highly mobile, easily transportable surface-to-air missile fire unit with eight Stinger missiles in two missile pods. It acquires, identifies, tracks and engages targets (low-flying helicopters or fixed-wing aircraft) from a stationery or moving position."
