Incidentally this is public facing Internet servers. The % -inside- enterprises us much much higher.
Tools like Active Directory allow you to scale enterprise operations, which is important for companies that have hundreds-of-thousands of desktops etc.
In any event your estimate of 99.9% is unlikely. AWS offers Windows based EC2 instances, and one presumes they're not doing that for 0.01% of the market. Azure will likely have an even higher %.
From the data though, not just guessing, I'd say it's about 20% overall.

I can believe private enterprise usage is higher, but I imagine FAANG and similar companies also have quite a lot non public Linux servers. Not trying to rebut your overall point, but I'm not sure the total non public % is much different.
Of course, we might not believe that all of those internet facing servers are of equal size and represent an equal number of servers, right?
We know that all the top 25 websites are 100% Linux and represent a lot of servers each.
Also a whole lot of that cited report seems to be misidentified. The top Windows site other than Microsoft properties listed is nih.gov, which looks like Drupal on Linux behind Akamai GHost -- all Linux.
I do accept that Windows is probably about 20-25% of server instances and slowly contracting. But public facing webservers and the infrastructure that directly supports them? Nothing close to this.
