If you're starting from zero, sure. Moving all employees in Russia to another country (and/or firing/replacing them) sounds like quite a major headache to me.

Sure on a 6-12 month timescale. Beyond that it seems much easier. This is true of any infrastructure decision, they generally require work in the short term but are taken on to relieve pain and facilitate the ongoing future.

I definitely hope that this is how Google and Apple respond to Russia's actions here. But I can't claim to know the difficulties they would face on a 12+mo timescale.
