tl;dr: A firmware update scheduled for January 23rd will remove the ability of third-party software such as Orca Slicer or the Panda Touch to connect directly to your printer. Users of third-party slicers will have to export sliced files and load them in a new “Bambu Connect” app in order to start prints or manage the printer.
That’s ripe for abuse.
Sounds like they’re going that route that some other manufacturers and slicers are going for “public safety” by preventing people from printing things like guns, but then it’s going to extend to more under the same guise.
