The EU will rely on US tech forever because it is literally not possible to create an EU alternative in that business climate. There are no major EU clouds, nor are there any major EU software services and there never will be because the EU is the worst place in the entire world for startups (try starting a company in Germany or France).

SAP and Spotify come to my mind first. Some ex-EU services include Skype and Booking.com (latter might still be counted as EU service depending on definition).
