But when you buy the printer you still need to give it internet access / connect via their app, right?
There's also other limitations of it in features I don't really use, for example IIRC the RFID stuff they do with their print spools stops working.
But yes today there is no need to use their cloud services unless you want to control the printer with their phone app. And the printer works totally fine completely isolated from the internet.
The now aborted proposed update would have required using a binary shim from bambu with an embedded 1 year lifetime SSL cert to speak the the printer at all, even when in lan mode.
