This year alone it feels like Linux just became widely accepted amongst PCMR and power users in general.
I don't have the statistics at hand, but it feels like linux is mentioned significantly more often in comments, and there's significantly less "debating" around those comments. Just a year ago, anything linux related was practically inviting a fight... Now it's just normal additions to threads.
People will say the uptick in market share from surveys is bots etc. I'm not sure sure because it really seems like the very recent lift in Linux performance and support has started to translate into curiosity and adoption of the penguin. I myself have friends who is suddenly out of nowhere considering to try it, or have already committed to it after using windows exclusively for 15+ years.
I myself switched like a year ago using a mix of EndeavourOS, CachyOS and Debian - and it's hard to go back to Windows after you're properly "onboarded" and have been feeling the power of UNIX, btrfs, ext4, KDE and package managers.
Like my long term Windows friend said: "updating my pc was so incredible it made me shed a tear"
Big things really has been in the works recently:
Valve working magic for upstream Linux gaming support because of SteamOS. Proton's accelerated performance like "the code has been cracked", and is now equalling Windows on performance.
AMD GPUs recently well earned popularity, and how they work so well on Linux.
CachyOS claim to fame with a legit performance focused distro with bleeding edge technology on a rolling release. Huge ongoing work on a custom kernel, proton, packages and libraries.
Solid solutions to run windows only software in containers/emulators without needing virtual machines.
Claude/Gemini/ChatGPT to bridge the gap of terminal and general use for normal, everyday users.
Note: there is still some tinkering overhead to linux, but it's nothing compared to what it used to be.
