And I can tell that while at CERN, those using LaTeX on paper submissions were the minority, on ATLAS TDAQ/HLT group it was a mix of Word, and FrameMaker.
KolibriOS (https://kolibrios.org/en) is an active fork of the open source 32-bit version.
I don't think it matters since Universities will not be taking Google Doc submissions unless it's core ed classes, any beyond it will be LaTeX anyways.
Now, to put on the the "feedback is a gift" and "radical transparency" caps.
From the screenshot comparison in TFA: The new one looks all Microsoft-Ribbony. That's a huge step backward. The big strength of LibreOffice or Collabora Desktop Classic is that it has a sane UI/menubar visual paradigm. (Which MS obliterated eons ago.)
But let's talk about what matters: Collabora (the online document suite) is slow as heck.
It needs to be fast-updating for shared multi-user docs, like Google Docs/Sheets or Word/Excel 365.
That should be the top priority. Full stop.
LibreOffice works fine for desktop. But, for Collabora, the web experience needs to be fast. The lag in Collabora is simply unacceptable.
People expect online, and they expect collaborative, and they expect nearly instantaneous updates (at least not painful to type and wait for screen to update).
Talk about misplaced priorities. In my very humble opinion.
I think this matters for the paying customers of things like Collabora and LibreOffice, as they're using it in a work environment. Not at home.
Valve has good, stable funds to pay a team full time to build and support Steam OS which, over a long period of time and with enough user uptake, I think will have better chances of getting publishers on board with ensuring their games work on something that isn't Windows. Hell, they could probably make deals with publishers to say "hey, here's a pile of money to make sure your game works on Steam OS day 1, and put it in all the ads" and get the ball rolling that way.
Gaming is a tough space to crack. I think Valve's money and their history of supporting the most popular gaming platform on PC inspires more trust needed to make their platform a standard target.
Maybe I'm downplaying what the Bazzite team is actually doing, but from afar it is Fedora Silverblue with gaming related tweaks out of the box, probably targeting handhelds and common gaming hardware in testing.
The actual issue of adopting a new operating system is already rearing its head on this thread. "What's Bazzite? What's Silverblue? SteamOS, is that linux? Is that different from this other linux?".
There's too many options for someone that wants to sit down and play a game. Unless a major OEM decides to push Linux on their systems, SteamOS is generally the only real competitor in this space due to reputation and control of the PC gaming market. Time in the market, versus timing the market is what comes to mind here.
