Depending on the location, if their app collects revenue or is sold in a local then it has a formal presence, and is subject to the laws of that jurisdiction.

Depending on the location, if their app collects revenue or is sold in a local then it has a formal presence, and is subject to the laws of that jurisdiction. I can NOT release an app that violates EU privacy laws in the EU and expect that it will be allowed to be sold after the issue is discovered. In the case of crypto (what were talking about here) local laws would apply. If china holds tightly on to that ban, if south korea follows suit, and this feature is integrated, then they are defacto violating local laws and may be subject to local laws and sanction actions.
