Of course. But what if the holding lives in a country that don't enforce this (or is too weak to). Then all the subsidiaries are really sovereign from the host country perspective.

It seems the solution is ages old. Don't have the holding incorporated in an empire...

How would this work in practice? If the empire wants to get at your data, why do you think it would shy away from pressuring a country so weak that it can't afford to enforce this on their companies?

Then the empire just says that they want the data or you won't be allowed to operate in the empire, which would be bad for profits and anger shareholders.
