Not where, when. And the answer is never, because the EU regulates what companies themselves either can't regulate themselves because no one's willing to adopt the other's standard, or there's a position of dominance that doesn't even require collaborating with anyone else. And they do that for a pretty simple reason: to ensure that businesses do right by the EU citizenship. And they do that across _all_ sectors of industry, you only noticed the tech one because it's in the news you pay attention to, but everything from farming to textiles to tech to pharmaceuticals are heavily regulated so that the people that live in the EU can enjoy a reasonable standard of living.
