Why is that? AWS has availability zones all around the globe, and 8 across the EU.
Getting deeper into US clouds is not something which aligns with the "goal on the horizon" of most managements.
Today, AWS, GCP, etc. are omnipresent, so there are plenty of counterexamples; however, the growing concern is, "How do we become less reliant on AWS in the next decade?" There is no answer to that today, but this adds growing friction for any USA-based B2B vendors who implicitly say "we will increase your ties to the USA forever". This concern about hyperscalers predates recent counter-USA movements, and feels like a one-way road.
