It's an interesting case to me. The company I work for has been shipping systems on windows since the 90's despite pretty consistent requests from customers to ship hardware on Linux. 2 years ago we started creating our own Linux distribution and this year started shipping products on it. We still ship a lot of stuff on Windows 11, but that market share is starting to shift now. 10 years from now I could see us completely moved to our Linux distro. Now, what's actually interesting is that it wasn't customer requests or efficient capital allocation that drove this. Microsoft effectively forced us to do this against our will by a combination discontinued products and handling of Windows 11 and now that we've spent the capital we won't be going back.
To me, this is the way linux wins, if it does.
Product teams deciding it's easier to ship on + customers having enough linux familiarity (from their other projects).
And the current crop of Microsoft people on the Windows team don't seem to understand building a platform in the way 90/00s Windows teams did.
It's clear MS moved a lot of their smartest people over to work on Azure products.
You can't abandon Windows because of software X, Y, Z. Over the years vendors move to multiplatform as more and more customers ask for it. These changes are slow but steady. And one day you find out that the last "must have" software is not limited to Windows anymore. That's when the dam breaks.
Out of curiosity why a custom distro instead of one of the major ones?
We have some special cases I can't go too much into that lend themselves well to rolling our own and stripping things down as much as possible.
