I want control over what my browser does, not necessarily my operating system.
I'm highly selective over my software as I require it to fulfill very precise goals in the exact manner of my choosing. If it fails to do so, I'll find better software.
For example, I have yet to find an image viewing software that is satisfactory for my usage that exists for Unix distribution. I use an extremely niche, unheard of software that is 'Windows Only'. It's so niche that searching for the name of this software on Google only results in posts of me talking about the software. (I decline to name for privacy reasons.)
My operating system is a platform to run software. I'd hop to Debian or Arch in seconds if I could find existing software that meets my needs. While the image browser is one example, there are more that do not exist to my desired standards outside of Windows applications.
My desire for software that performs certain functions and in the manner I want outweighs my desire for privacy from my government and control over every system of my operating system.
ps:
I know your question was probably meant rhetorically.
