Most of their revenue is tied to other stuff though

1. Productivity / Business (~43%)

Includes:

Microsoft 365 (Office, Teams) - these can be likely ported to Linux if they're not already since they also work on MacOS? LinkedIn Dynamics (ERP/CRM)

~$120.8B

2. Cloud (~38%)

Includes:

Azure (runs on mostly linux, and moving cloud provider as a big corp is expensive, I don't see massive companies stuck in azure infra moving from it) Server products (Windows Server, SQL Server, etc.)

~$106.3B

I fully support the demise of Windows as an OS

But microsoft as a company has shifted away from Windows as their source of revenue, and will probably not be impacted too badly if it were to die completely.

The French move will hit the Productivity/ Business segment. Their motivation is to limit extra-European dependence so they will look elsewhere for this.

Similar to Germany with its DeutschlandStack and some migrations already ongoing.
