Like the other reply says, Linux already won on the server level where all the hype was 25 years ago. Now it's different but there's a lot of excitement still thaks to Valve's efforts to make gaming viable on Linux and to make ARM/x86 porting easier. Plus there's been a new wave of new users lately thanks to influencers recommending Linux in the wake of Windows 11's horribleness.
late 90s Sun and other companies were still selling high end workstations and servers running unix, and Microsoft was trying to dominate the server marekt.
Linux won most all that and now there is no competition; that's why it seems quiet.
