He is free to remove the part where it spoofs itself as BambuStudio and do whatever the hell he wants with it. He can probably distribute it with the spoof and continue without actually getting sued because they are likely fixing this as I type this. If they do sue him it will be for unauthorized use of their cloud services. I do think they'd have to sue individual users.
Accessing my garage and using my tools == using Bambu's cloud infrastructure, which they clearly do not want him (or apparently any non-BambuStudio clients) doing any more.
