I think the point of my comment is being missed a bit here friend. Servers and backend use Linux, sure. The actual number of Linux users is likely under reported as you say.

But I have yet to see Linux used as a workstation OS in a place of business. Every doctor, insurance broker, banker, registry, and retail place I’ve visited were using Windows machines to access their infrastructure. If Windows creates vulnerabilities at entry and exit points it can still compromise information.
