From a personal standpoint, it sucks, but from a legal pov, you can't have companies that can contain huge flows of money working in your country for free.
If it's demanded, it's demanded.
These companies have legal departments that SHOULD have taken care of it.
Seems to me they just want the carrot, but not the stick.
Besides, there's no reason for these companies not to work again over there if their situation is normalized.
It sucks, but it's the way it goes.
