Windows users, and Plone

Today, I would like to ask the Plone community a question. Please, it is not my intention to offend anyone. It is a feeling of Windows user who really likes Plone that I'm trying to express.
Why among CMS (opensource), it is only at the Plone level that one can sometimes have the impression that one discourages Windows users a little bit?
And yet I can assure you that there are a lot of Windows users fully committed to Plone.
If there are some who think that I am wrong or that my feelings are unfounded, in advance, I apologize.
Thank you for your attention.
