An open threat like that would be the best case scenario, as it would (hopefully) cause a reaction in EU countries trying to get rid of this yoke. Instead usually it happens through backroom dealings, or just the services being a nuisance to competitors while being helpful to friendly companies, and thus the target country is drained of its resources and economic independence, slow enough to not provoke retaliation.

With the exception of the current US administration, hostile countries and corporations try to appear non-hostile when possible.
