 in the meantime, whilst such a court case is underway, they're losing
literally billions due to the upstart having "stolen" their knowledge.
a CSMC employee actually did that to TSMC: worked on TSMC's 28nm line,
went back to China and started CSMC's 28nm line with the knowledge.

 it took years for the court case to go through, as it's in a
different international jurisdiction.
