Here's EU telling Microsoft how to conduct business globally, back in 2004 - https://economictimes.indiatimes.com/news/international/ms-s... - 'help rivals connect their products to the Windows operating system.' does not mean 'EU rivals', but any 'rivals', outside of the EU as well.

'Intel v Commission (C-413/14 P, 2017)' is another case where EU Antitrust explicitly punished global conduct outside of the EU.

Right now, with exception of antitrust, EU laws only incidentally affect global conduct, e.g. once a business is compliant with GDPR, it's often too costly to restrict compliance just to the EU. Nothing stops that from changing. EU absolutely can make a law that obliges e.g. chat app providers to either apply EU privacy standards globally or face bans/fines/seizure of their EU operations.
