At the same time American companies are increasing their control over their established base. MS accounts needed to log in to Windows. Google eliminating other app stores. The move from desktop to phones for most users.
Most businesses are still moving to a range of American dominated cloud things. Not just hyperscalers, but SaaS is also American dominated.
The very fact that moving just 1,200 people to NextCloud is such big news underlines just how small the movement the other way is. This is despite continued reliance on Outlook and Teams!
The only way I see the grip of the US loosening a little bit is if continued outages persuade people they cannot rely on the hyperscalers to such extent there is a more back to on-prem and smaller suppliers, however the US has unshakeable and increasing control of end-point device.
