Will this mean that Bambu will withdraw from the Australian market? Possibly maybe probably, but the ACCC takes a very hard stance against bait and switch.

Yes, it's not as simple as that, but it's not that impossible either.
This kind of firmware update to remotely disable feature is also illegal in the EU
