I did. Some of my clients by design host everything on German servers of Azure and call it a day.

1. the USA has secret FISA courts - defendants cannot even say they whether they were summoned, let alone what case or judgements were
2. the CLOUD Act compels American companies to hand over data, regardless of where its hosted.
So your German companies would never even know if they have been compromised.
But ignorance can be bliss.
Accepting the risk isn't the same as finding a way to mitigate it. Plenty of EU companies just happily use US cloud providers, that doesn't mean the risk doesn't exist.

I've seen zero cases so far where "physically present & managed in the EU but still owned by a US company" is sufficient to mitigate the typical US hosting concerns.
The threat is that AWS could be forced to a) suddenly pull services or b) spy on data by the US administration. That the DC is located entirely in the EU does nothing to reduce that risk if it's still fully owned by Amazon.
The was already a major concern for the last couple of years given the successful legal challenges against the privacy shield as sufficient data protection to give personal data to US organizations, and is way more of a concern after issues like Karin Khan and the ICC being suddenly cut off by Microsoft - it's clear that US companies literally can & will suddenly block key business services on administration whims. There's plenty of organizations where that's unacceptable risk.
