> The reality is much more mundane: many Chinese companies do not understand the expectations around open source.
Except that Bambu is not a small player in the game, and they made threats of using the DMCA which shows they are fully aware of "western" IP law and the nature of licenses, Open or otherwise.
Aren't you saying the same thing as parent? The expectation is usually NOT to send DMCA notices, so if they do, doesn't that also allude to what parent said, that they don't understand the expectations around open source?
They understood enough to know that they could not claim a license violation but invoking the DCMA, specifically the part about bypassing digital locks, they could intimidate a developer.
American lawmakers and politicians are technologically ignorant, and Americans in general see programmers as existing on a spectrum with boring nerds on one end and hackers on the other. Bambu was betting on easy support by painting the developer as a hacker who was "reverse engineering" their "safety features". What Bambu failed to understand is that the people who make and use Open software are not average Americans, they are tech savvy, interested, and loud.
