TSMC is doing it under pressure by the US government and it is not certain that it will happen.Why are you cherry picking whatever suits you? These companies saw a boom during corona years and now gradually return the pre covid times. But on the other hand there is Intel building a massive new factory in USA and so is TSMC.
It really makes no sense to do a company to company comparison to defend the state of Turkish economy.
It is not only to flatten the employee bubble that happened in the media companies caused by the pandemic but also in preparation to a major recession of the entire economies after the war in Ukraine and power struggle between US and everyone else, China in chief.
You don't see my point that our people are better taken care of at home than being in some foreign land as their economies are bleeding and jobs are being cut. You still think that we are losing brain power. Our engineers work remotely when they need to rather than moving abroad.
