They use an online MQTT server instead of the local one for the following functions: initiating printing, heating the nozzle, and heating the heatbed. (see https://www.allaboutbambu.com/2024/06/14/p1p-p1s-new-firmwar...)
On https://forum.bambulab.com/t/bambu-lab-mqtt-limitations/8344... you can see their MQTT server got DDOSed by some faulty 3rd party "client".
I don't think it's so much about security of the users as much as it is about their own.
In lan mode it doesn't use anything remote and works just fine completely isolated.

Right, when you use 'cloud mode' then bambu controls the printer, and your own control has to go through them.
