A vast majority of the people on Lemmy use Linux. Or, at least, the Linux users on here are the most vocal about their OS. Just type in “Linux” in the community search, and you’ll find dozens and dozens of linux communities with thousands of subscribers, compared to a handful of Windows communities with only a few hundred subscribers.
It’s a shame this isn’t a permanent thing anywhere, I’d drop everything to go at least once if I could. Thanks for showing this!
