I wonder what their motive is at this point. Are they actively trying to commit fraud and use false legal claims to silence their users, and have no intention of delivering any printers? Though I haven't seen the build guide, releasing it would seem to imply they are still trying to deliver or at least produce printers, which if that's the case, why would they alienate their users with such heavy handed tactics.

Or is the product that bad, and they know it's that bad, but don't want to take the time to correct the issues that they just keep pushing ahead and use their 'legal' tactics to silence any reviews or comments about it...
