weev got convicted for something pretty similar to this. His conviction was vacated, but he did spend time in prison for unauthorized access to an AT&T server that only required a specific user agent and a guessable numeric device ID number.

At least in the US, the law against unauthorized access to a computer system has no requirements for how good the security has to be. If you should reasonably know you're not supposed to be using it, that's potentially enough to make it illegal.

I checked and in that case [0] specifically, the court specifically doubted that such access was violating any applicable laws. Course, it got vacated before that could be properly addressed and this seems to be specific to NJ so if someone knows a broader case, happy to read up, but to me this makes the argument stronger that there is no reason to just presume such a "bypass" (if that counts, many of us have "bypassed" a lot via reading robots.txt, etc. in our youth) is inherently illegal. Again, happy to read if someone can provide a source saying something else. If Bambu want to argue EULA, go ahead, but let us not give these entities the ability to just wish something illegal because they simply dislike it, when there is no evidence it is.

Am currently somewhat into the topic of UAs for a personal project (not connected to Bambu printers), so am honestly interested for any tangible information, I just dislike us assuming something illegal because a corporate entity views it in a negative light.

See State v. Riley, 988 A.2d 1252, 1267 (N.J. Super. Ct. Law Div. 2009). Although we need not resolve whether Auernheimer’s conduct involved such a breach, no evidence was advanced at trial that the account slurper ever breached any password gate or other code-based barrier. The account slurper simply accessed the publicly facing portion of the login screen and scraped information that AT&T unintentionally published.")

There was more than one court involved. He was convicted. Then he appealed and the appeals court vacated the conviction. So from one perspective, "the law" as a whole decided that he wasn't guilty. From another perspective, he still got involuntary lodging courtesy of the state.
