The way i see it, if Amazon want's to close down its data centers, they either have to pay a lot to get the infrastructure out and ship it to a different region. Then a building predestined as a data center is available for a european company. Or they sell the building and infrastructure and a european company can get a fully equipped data center for cheap. Or Amazon just pays proper taxes as it doesn't want to lose access to the EU market.

They will threaten Germany and the EU and they will complain, moan and cry about it. But when the decision is made they will pay their taxes and keep access to the enormous market that the EU is.

Yes, you would. Some of the best alternatives are German (like Hetzner) and they don't take off because of US government influence stopping local businesses from accruing profitable contracts both in the private and public sector.

I'd love to see tariffs on US tech Invaders and a moratorium forbidding US companies from buying EU direct competitors for 20y. A cursory look over the meta anti-trust suit should tell you why. Meanwhile MS has killed Nokia, Skype, still owns (and continuously enshitifies) Mojang, just to name a few.

Who cares, OVH also has Data Centers in Germany. The demand for those services won't disappear. These people will just be employed elsewhere
