There is no security threat, it's an excuse. I own a printer and operate it in LAN mode. It requires authentication with 8 digit code.
If you think they care about security, let me remind you that this company used to connect to their cloud in plaintext. The only security they really care about is that of their revenue.
If they actually cared about security, they would let us disconnect these printers from the cloud completely and allow us to manage our own mTLS certificates.
I don't know the details or if it's true, but someone who was in the firmware beta claimed there was //commented-out code about different subscription tears. Maybe just a test, maybe for print farms .. maybe it was all a lie.
But yeah, the enshitification economy has made people justifiably paranoid that if a product starts exhibiting new capabilities or features that would seem to support or enable a move towards subscriptions, it’s a good bet that that is in fact the trajectory of the platform.
But afaik Bambu has neither confirmed nor denied that this is in the works.
