I'll just list some I remember
Their slicer has a fork called orca which included some nice extra features and calibration tools which work for all machines not just the Bambu ones. In the latest update of their slicer they just copied all the code from the fork but never mentioned the person that did all the work until they were publicly called out on it. Which seems to be a recurring theme.
Also many functions of the printer are locked behind it being always connected to the cloud which has been proven to have multiple vulnerabilities. One of the most annoying is sending files over to the machine over wifi is linked to the printer having acces to the Bambu labs servers which have been experiencing some downtime lately. Meaning a lot of functions of the printer are only there as long as Bambu labs exists.
