I have an Ender 3 too. And I have a Bambu machine - that I leave offline and use via microSD card as the Ender got me used to.

I get it. The convenience of networking - when it works FOR the customer - is great.

But networking controlled by corporations is a path to enshittification.

At least your use case would be served well by enabling LAN mode, which doesn't let the printer talk to the internet, even if you want it to (and I want mine to).

The problem is trust. I don't want to get into an adversarial relationship with my printer over networking.

I could enable LAN mode and trust the mode does what it says.

I could trust others firmware reverse engineering to verify LAN mode does what it says.

I could isolate it on it's own wifi and I could block it at the home firewall from accessing the internet, to be sure.

But it was easier to simply leave it off my network.

Yeah, fair enough. I have a VLAN with no Internet access for those devices, it's convenient.
