I already said this over at reddit.com/r/knifeclub, but might as well say it here too:
Note that the first several paragraphs discuss the events surrounding Microtech's decision to rip off the design of the ZT 0777, but from the seventh paragraph on (starting with "It is, however, important to note...."), the letter switches to an entirely different subject, namely, the dispute over the sub-frame lock mechanism.
Essentially, Microtech admits in this letter that the Matrix is a ripoff of the 0777, but it was purportedly done in response to a threat by unknown KAI employees that ZT was going to build an OTF that would "remove Microtech from the OTF market." Even assuming this is true, no explanation is given for why Microtech/Marfione continue to sell a ripped-off design despite the fact that ZT never released a single OTF, let alone one that's a Microtech ripoff.
