2 questions:
1- Is it legal to just let go of people just because you don't need them any more, although you are profitable? Whats the difference between this and firing someone?
2-I doubt PC market is getting smaller. The world is dependant on computers more than ever, sure people buy less desktops, but there are servers everywhere and in every office. Also, intel can take on ARM easy. Lets not forget who's running like 70% of the computers in the world.
The PC market has been getting smaller and smaller for a decade now. Enterprise does not need the latest and greatest chips. Especially when a lot of the hard work is being done behind the scenes on the cloud now. Intel is finding it harder and harder to charge a premium for their newest chips that only support a niche market.
