You're seeing people wake up to the threat now, with the opposition against Kyndryl and the Nexperia thing.
Somewhat more controversially, I'm also worried about the French government owning large parts of the Dutch defense industry through Thales and Airbus. (And, to a lesser extent, German and Spanish governments.)
Very little of the Dutch defense industry is still Dutch-owned. Only Damen comes to mind.
None of the sharks ultimately ever managed to agree who gets to eat it- because whoever did would upset the balance between the sharks.
But China and America are mega sharks who don't care about balance and want to eat everything or die trying.
