i would not be surprised if more of their actual development resources were being put into linux than in windows at this point
lately windows is just a dumping ground for trendy-looking electron apps and the latest cloudshit
Oh yes. Linux has been a huge priority over Windows for quite a number of years.
This shift in focus happened due to prioritizing Azure (and declaring Winows legacy and shifting all development of it to India).
Cloud today is virtually a Linux-only play. The vast vast majority of customer VMs running in cloud are running some sort of linux. The most recent info I had was that a number of years ago RHELand derivatives made up ~60-70% of all paying Azure customer workloads and other Linux the majority of the remainder. The amount of Windows VMs is in the single digit percentage.
It is like the "Linux desktop percentage but in reverse".
If Microsoft knows anything they know how to follow the money and Windows is not where the money is.
All high-value work today and all engineers at these sites today work with Linux and focus on Linux. This includes premiere campuses like Redmond.
I think WSL was a last attempt to keep Windows relevant for enterprises but if you are going to run and develop on Linux why not just run Linux. Why go the detour of using WSL? And that is why it failed to take off.
Then in the last few years AI really started to take off and 100% of all AI work on the server and training side of things is Linux. Making the Windows itself even more irrelevant in the eyes of Microsoft.
Windows still exist and will continue to exist but Microsoft is no longer putting any priority into it or making any significant investment. It has all been shifted over to India and is never coming back. All high-priority work and engineers are 100% invested in Azure and AI and that is basically 100% Linux.
EDIT: Just look at how Windows have evolved since around ~2016-2018. Virtually nothing of importance has happened aside from ads and tweaks to the desktop UI. You can se that for yourself. This is what happens when things are deprioritized. Things stagnate and innovation grinds to a halt. Don't take my words for it. Compare innovation velocity in Windows from the decade before ~2016 and the decade after.
