Whether I participate in this discussion or not, I may finally still decide for myself.
As I already mentioned and as Adrian also wrote, it is about the regulatory rules. For example, software is also subject to export regulations. In Swisscom software this is clearly noted everywhere. Namely, for example, Russia, Iran, Iraq or North Korea.
Sure, you could unlock the apps for USA or UK, but it also means that the apps must comply with the regulations of the respective countries and authorities.
For a small number of affected customers, Swisscom will probably refrain from investing such an effort, especially since all functions of the MySwisscom app can be accessed within MySwisscom on the web, for example. The same applies to Cockpit, Mail, BlueTV or simply MyCloud.
As for the competition, let me put it this way, the other providers, especially Yallo, often also point to users from abroad (such as the “poorer” euro area), so the provider’s customer base is significantly more from abroad than Swisscom. But even there, web apps are now so widespread that native, normal apps are becoming obsolete.
