And this is why the Google security folks don't let employees use wireless keyboards unless they're bluetooth, and above a certain bluetooth protocol version at that. Not that this analysis at any time conducted attacks on the bluetooth protocols - every single one of these keyboards had a secondary 2.4GHz dongle and just happily transmitted everything over that. I'd have liked to know whether they're trying to transmit to that dongle all the time or whether it turns off when the bluetooth connects!
