This flat out isn't true. Police forces / investigative authorities have been collaborating with one another since 1923: https://en.wikipedia.org/wiki/Interpol . We have tons of examples of this working for the digital world as well (like Proton complying with Swiss legal orders at the behest of non-Swiss police forces for illegal activities in other countries).

The trick is to host your data in a country with a strong rule of law, and avoid illegal / geopolitical lines. If you're an American company hosting stuff in Russia, you can bet the GRU/SVR would be very happy to abuse it. If you're running a torrent site in Ukraine, you can bet the US would be very happy to claim extraterritorial magic jurisdiction and get you extradited from Poland.

As a French company, you're already beholden to French law and French legal decisions. "Data is hosted in Hong Kong" doesn't matter in the slightest, it only exposes you to more risk.
