I find this a cynical take as far as EEE goes. But even with Microsofts mostly solid efforts into open source I find myself a bit skeptical as well.
Most recently with the Live Share extension for VS Code. From skimming the licensing it is only to be used with the Visual Studio family of products. Which is an incredibly disappointing approach.
I think this is simply about ML and GPU compute for WSL. And I think Microsoft is genuine in that it sees business value in doing open source work, integrating well with Linux, etc. But at the end of the day the business interests are there and different parts of the company can be motivated quite differently.
Some skepticism remains warranted.
