I don't think you are an outlier at all I just think people tend to have narrow views of what is happening based on what they work on and what they see.
And I happen to agree with you and I'm not a MS fanboi at all...
I work for an IT consulting company and have worked on projects for hundreds of companies and yes often (but not always) their web servers, app servers, etc are linux and they may have a few other linux servers here and there but from what I have seen that usually is only about 10-20% of their servers total. The other 80-90% are Windows servers.
Windows servers running Exchange, IIS, Sharepoint, Lync, Skype for Business, MS SQL, Active Directory, Print servers, File shares, Office Web Apps (or Office Online Server as it's now called), WAP, Azure Sync and now even running Azure.
And with the *huge* increase of companies moving to Office 365 now the number of Windows servers is only growing. MS won't be IBM any time soon with their VERY strong position for cloud services all related to Office. And now as previously mentioned you can now run the Azure stack in house on your very own Windows Servers those numbers will only keep growing.
