And now you know how much you should trust a Chinese company with your
intellectual property...

Though there might be exceptions, if you're paying them to defeat the
code protection on a programmed flash MCU, you're quite likely
'trusting' them with someone else's IP.

Outsource to a country that doesn't respect IP, and that is what you get.
