No one's angry. This just gives a bigger impetus to de-Americanizing the tech stack. I've recently taken part in a decision at our university to use a non-US based cloud storage provider for some relatively sensitive health data. The risk is just too high, and justifies paying a slight premium elsewhere. Sadly we're not likely to migrate away from Office 365 over here, but for any new vendor decisions, US now definitely equals premium for risk of fuckery.

I can perfectly well blame my home country of America for this. This is terrible business policy that destroys America's business advantages with unjustifiable federal overreach.

That's an issue with America. For all American businesses.

What should we be getting angry at Europe for in this context?

It's funny seeing Americans start to repeat Russian line of thought.

"Who allowed you to live like that"...

The Trade Balance between the US and Europe was very balanced if you included services. So the US wasn't getting ripped off in Trade.

The dumb actions by the current US Administrations give the EU a big incentive now to buy their services elsewhere in the future, so Trumps fever dream about the disbalance might come true thanks to his own actions
