As much as I'd like to see Linux gaining traction, I have a hard time believing market share is as high as StatCounter reported in some places. For example in Canada, Linux usage is at 1.99%, which even still seems high to me. That's 1 in every 50 desktops. Anecdotally I can think of only 3 people, including myself, who primarily run Linux on desktop. In corporate environments, I have only ever seen Windows, or sometimes Macs deployed to employees. Even with the hate on Windows 11, it still works for most people, so they upgrade to it (begrudgingly, if they care at all), or simply buy a new computer for it. I truly wonder who else out there is running desktop Linux here in Canada...
That being said, I am less skeptical of the growth in users in India, but not for the reason the author listed. I think it's more likely that it is growing in popularity due to its cost (ie, free), as well as the fact that many distros are more lightweight than Windows, which especially benefits older or cheaper hardware. India is still a developing country and I'd imagine many don't have the resources to buy the latest hardware, and instead will make do with what they have or what they can afford. I think this will continue to be a boon for Linux in the developing world as Windows is not getting cheaper or faster.
Overall, I think Linux has nowhere to go but up. Once Windows 10 finally goes EoL, we may see more people looking to make the switch.
I mean, they themselves called it.
