> On GNU/Linux, is this much of an issue? Even if you ignore the proprietary software side of things (which is an issue unfortunately), if an application is misconfigured or exploited then this is one way of detecting and blocking that. And sometimes there's some weirdness like VLC will sometimes make network requests to get album artwork even though I'm fairly sure I've disabled that feature. It's better to have a tool that screams about applications that are safe than it is to try to patch things up with configuration options in every app on your machine.
