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. > > Bottom line is, we're literally decades and hundreds of millions of > > dollars away from libre foundries.
