I guess they eventually read their own local (US) laws and figured no one cares about that effort since Amazon is still covered by CLOUD Act, regardless of what ccTLD they happen to use for their landing page.

> The CLOUD Act primarily amends the Stored Communications Act (SCA) of 1986 to allow federal law enforcement to compel U.S.-based technology companies via warrant or subpoena to provide requested data stored on servers regardless of whether the data are stored in the U.S. or on foreign soil.

Once that was in place, AWS could host their "EU" servers on the moon for all I and others care, still not a solution to avoid the claws of the US.
