The current environment incentivizes expanding the developer ecosystem, hence DX investments.
This is simply Window's attempt to build a new walled garden. If they were actually serious about advancing the state of civil computing, they'd make the NT core available as a microkernel that can be modularly placed into the Linux ecosystem. That is the _one_ thing I can think of which might raise my opinion of them (and I'm sure they lose sleep at night, knowing they haven't got my endorsement).
Hopefully, nobody is having the wool pulled over their eyes. Don't get me wrong: their incorporation of a TTY-like interface into CMD, and the Linuxification of Powershell, demonstrate the craftsmanship that Microsoft pride themselves on. It's good tech, but tainted. I will never trust Microsoft after the RDP fiasco.
Until they make moves to break down the walls of their garden, they're just another barrier.
Programs bult for Linux suddenly can be run for Windows users. That's a boost in adoption potential for Linux programs (large part of the ecosystem). And adoption is very impotant for further development and success of software.
On the other hand, for Linux users this makes Windows more attractive - why not choose Windows for your next laptop, if all your Linux software runs there. That undermines Linux userbase.
But overall, I feel WSL is good for Linux.
I do see your point, however, and I hadn't thought it of that way; do you see anywhere the community might pick up on this for some benefit?
It could mean that people start realizing that there's gaps between Windows and Linux that need to be closed to make Linux more attractive to users. Alternatively it could mean that people don't acknowledge those gaps and instead gripe about EEE.
I know which outcome I'd put my money on.
They are good, just as any public can be good company. IE. Just a little bit more sensible about cooperation instead of demolition.
