I can already write the headline of what this will be in five years...

"Swiss Government Moves Back to Cloud After Discovering Cleaning Staff Had More Physical Access Than IT Security Team"

The encryption requirement makes sense on paper, but it basically breaks the whole value proposition of SaaS. If you need true end-to-end encryption where the provider can't see plaintext, you lose search, real-time collaboration, most of the AI features everyone's been bolting on lately, etc. You're essentially left using these services as fancy file storage with your own crypto layer on top.

Which is fine for IaaS use cases - spin up VMs, encrypt your disks, manage your own keys. But for productivity software like M365? The Swiss government is basically saying "yeah you can use it but only in a way that makes it almost pointless."

The Cloud Act part is what really matters here though. US providers can be compelled to hand over data regardless of where it's physically stored, and they've been pretty clear they'll comply with US law over local data protection rules when push comes to shove. For a foreign government storing legally confidential citizen data, that's a real problem. I suspect this will get quietly ignored like the previous declarations, because the alternative is either building everything in-house or relying on local providers that frankly don't have the same feature set or reliability.
