It's not like you have a choice, the printer doesn't work locally unless you enable LAN mode, and then it only works locally. Bambu make you pick either "closed servers" or "the mobile app doesn't work" for no reason.

I'll chip in to this developer's legal defense fund because I want to be able to do whatever I want with my printer, and "I can't do what I want with my printer" is a bigger problem for me right now than "the developer made a TCP connection on my behalf to a server he didn't own".
