"you only had to change one setting on the printer itself, and optionally block the printer from Internet access via the firewall to prevent automatic firmware updates and telemetry" - "only" is doing a lot of work here. Yes, this is easy for us, but that part alone is beyond most users.

I have a P1S myself, and I find Bambu to be a strange company. They're one that has benefited tremendously from OSS while sometimes violating both the ethos and licenses.

They specifically engineer it such that your prints need to go through an intermediary even when it could send it right to your device on a simple network. That'd be like a laserjet routing through the cloud instead of going to your device. With nothing much in the way of encrypting your designs and protecting your data, it feels like this was done on purpose. Given the shameless track record of many (most?) Chinese companies on IP, my assumption is that they're mainly doing this to steal designs. The juxtaposition of their poor track record on OSS, what seems like a shady approach to privacy and IP protection, and the aggressive legal posturing - all sum up to what I think is a very untrustworthy organization.

Luckily my designs are in the "look at this trash" territory, so I don't have anything to worry about, but I certainly wouldn't use this for important work.
