Europe gets serious about cutting digital umbilical cord with Uncle Sam's big tech

No Swedish governement agency can freely choose a technical solution. Almost all such choises fall under a public procurement, which are heavily regulated. They can demand that the service supports certain things to exclude actors, but if too strict I think the procurement can be overturned. In some cases a US actor can just offer a low enough price and the agency more or less have to pick them.
