At this point it is kinda an open question whether using AWS/Azure/GCP for anything involving PII is even fully legal under EU/EFTA law. I know at least my employer is working towards having more options to jump ship at a moments notice these days.

I think EU/EFTA is large enough to enable the growth of at least one 80% offering given enough time. Or otherwise large enough as an economic bloc to force America to stricter legalisation so that they can use and depend on the American offerings.
