That's a hard one and you can be pretty sure that any figures are
bullshit or at least cherry picke (do you measure revenue, install base,
hardware as shipped...)

Most other stats I can quickly find put Windows at ~50% of server
market, Linux at ~15%, Unix at ~20% and Other at ~15%

Also; is a Linux-back VM infrastructure hosting Windows guests counted
as Linux or what?

They're right, no one knows Linux. No one uses Linux. Just like no one
knows or uses NTOSKRNL but they all know and use Windows.
But people do know about and do use RedHat, CentOS, OpenStack, Amazon
EC2, ESX, Anrdoid etc.

One reason why MS is pushing some updates to Linux is because around 20%
of guest instances on Hyper-V are Linux-based. So that's MS acolytes
choosing Linux and not at inconsequential numbers.
