In the real world that specific “anti cold outreach regulation” is enforced. You can very easily find examples online of companies being fined for a single email. The German version is a stricter version of EU regulations IIRC so you likely have a more or less similar situation in other European countries. You seem to want to talk about jurisdiction, which is something that feels irrelevant. The reasons companies have a presence in Germany is exactly the same reason they have a presence in the US or any other country where they want to sell their services, but that has nothing to do with the topic at hand.

I will stop here, the whole back and forth feels unproductive
