Bambu had its requirement to go through their servers since before the Ukraine war, though it has gotten progressively harder to work around.
There is no requirement to send prints through their servers. My P1S has never been logged into their cloud service in the year I've owned it.
...nope...?
the Ukraine war started in 2014 technically. But even if we go to the "current" wave start, that was 24 February 2022[0].
Bambu Labs released their first printer (X1C, on kickstarter) on 31 May 2022, let alone their "must go through cloud service" restriction starting in early 2025[1].

There is still no hard requirement that you go through their servers. The printers support a mode where they can only be accessed from the local network.
