it says it right in the description, which you don't need a subscription to read

> In 2019, the Windows operating system was used on 72.1 percent of servers worldwide, whilst the Linux operating system accounted for 13.6 percent of servers. Compared to 2018, both companies experienced an increase to their overall market share.

I don't think what is described as unbelievable is that the source claims that, but that the claim is true.

(And since it describes both “Windows” and “Linux” as “companies” that gained marketshare, I’m somewhat suspicious of their information gathering.)

But not being registered with them, I don’t have access to what passes for their detailed source information for that claim.

That's just unbelievable on the face of it.
