Well, to give them the benefit of doubt, this monitoring could be done in a (more or less) privacy sensitive way, e.g. by analyzing the frequency spectrum of the audio input without actually recording or transmitting it, or as others have suggested, maybe they're just checking if the microphone is in use. And for the network they're apparently only monitoring the ports, not the actual data. But still, it sounds like a feature for which they should provide an option to turn it off - or, even better, make it opt-in.
