At the very least I hope it’s hosted by someone outside the US so it’s out of reach to the authorities.

The default behaviour for SIGTERM (and most other signals) when unhandled is to terminate the process, so you might as well be sending SIGKILL. It won’t keep running unless specifically coded to catch the signal and do nothing with it.

A lot of GUI apps unfortunately don’t catch SIGTERM, so it doesn’t make much of a difference. A lot of them put their “exited normally” into the “the window was closed” handler.

For GQRX that might even be intentional, it’s very unstable at times, and you do kill it pretty often. So they probably assume if it got SIGTERM, it was frozen and the WM offered the user to kill it and clicked yes.
