Yes, but not all devs within microsoft are allowed to work on non-ms foss projects. I assume wsl devs are allowed to send stuff to linux but visual studio devs probably are not.
The wrote and released VS Code - a completely opensource development environment. If they wanted to patch Grub I bet they could have found the permissions internally to do that. Microsoft is a lot more open to OSS contributions then they were in the past.
Not saying youre wrong, but you took the wrong project as an example hehe.
Visual code is not open source. Its core is, but visual code isnt.
The difference is what visual code ships with, on top of its core.
Its like saying chrome == chromium ( it isnt ).
Visual code comes with a lot of features, addins and other stuff that isnt in the core.
.net debugger for example, is not found in vscodium ( build of the vscode core ). And there is more stuff i cant think of now but have come across.
Source: been using vscodium for a few months instead of vscode
Sure, my bad. But it does not change my point. They have released stuff as opensource even if not all of it. Which means they can if they want to.
