Perhaps, just perhaps, a crew might not feel the need to listen to a match if they could just get a quick update from an ATCO instead - then they wouldn't crash, as they could then get on with being professional!
No, notso, we're not a results service. Instead, we are part of a team dedicated to getting our passengers from A to B in safety and comfort. Nothing more. God forbid that we should actually consider their journey to be more fun and enjoyable, and take a little time out if we're not doing anything and nor is ATC. We might lose the image of being untouchable skygods! Oh - and the FO isn't there for fun, either. If he cracks a joke, it is definitely bad form to laugh at it. He might think he's your equal - very unprofessional. All communication between the two pilots should be operational only. It would, of course, be extremely unprofessional to say anything at all to the cabin crew beyond what is strictly necessary for the purposes of the flight.
For heaven's sake, notso, loosen the sphincter a little. If the pax have a good time, they're more likely to come back. If they think you're an uptight anal retentive who relies on being stuffy and pompous (of
course I'm not saying this about
you!) they will look elsewhere next time.
