The issue with the grouping is on the KEF implementation/hardware side as far I have been told.
limitation due to the way KEF implemented their system… the work around is to get an endpoint like an RPi or Allo Digione Player.

Don’t know how true/accurate this is as I have very little experience with ATV.
You shouldn’t get kicked or banned. KEF is trying to keep a positive note to their FB page, which is their prerogative, it just comes across as trying to hide the peanut, IMO. They should fess up and admit they released too soon…
I have never had an issue updating the firmware. I use a PC, however and I did here of some issues early on with the MAC version of the updater, but those should be fixed by now.
