I'm not sure how accurate StatCounter is, given that most Linux users use adblockers. However, according to it, Linux has almost a 14% desktop share in India.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I'm not sure adblockers change the OS they report. Other tools I know for a fact do it.
Edit: However, as @aebletrae@hexbear.net mentions, adblockers don't have to change what OS is reported to change the overall statistics. They explain how in a comment below.
I think the assumption is not that adblockers alter the user agent info, but that they also block other resources, so StatCounter won't see those users at all, leading to under-reporting.
Ah. This makes sense! Thanks!
There are also other ways to fingerprint a derive based on how your cpu renders the html canvas.
