Just wondering if we could please cut the snark and name-calling out, and return to acting like adults?
I had AirPort routers in the past, as well as a Time Capsule at one stage. Good devices for what they were, however I did notice functionality being wound back with later device releases - SNMP, for example. SNMP isn’t something the average punter wants/needs/knows about but it’s very handy for those who do.
The AirPort Utility is a nice and easy to use piece of software making router configuration pretty easy - great for the target market, especially once the iOS version was released. Compared with the alternative, the user experience (particularly for less technically-minded punters) of the AirPort devices is excellent - this loss is a shame IMHO.
Sharing USB devices/audio streaming were not functions of the AirPort devices that I personally used - I too have migrated away from AirPlay entirely. I currently don’t have any AirPlay capable devices, although I understand my Sonos Ones will be AirPlay 2 capable in the future - I don’t anticipate using this, preferring to use the Sonos controller or Alexa to control music playback from my streaming service of choice.
