A proprietary software company never makes a "move toward open source". Microsoft released some things with source simply to sell more proprietary software that does not respect user freedoms.
Open source and free software is a philosophy and ideology. Microsoft is incompatible with it no matter what licenses they use.
Microsoft never embraced open source. You can't claim
that until and unless Windows is released with source as free software, which will Never Ever Happen.
MSFT is indeed embracing open source -- prediction -- a polluted and key-controlled Debian will be inside the next OS, filled with Azure management python packages and adware. Second, Canonical as indentured servent, will deliver anything that Redmond requests as snapd, with phone-home welded ON and more expiring keys.
You are not the customer here. You are a cog in an industrial machine. It is the executive management that has power, and you will know it every day. MSFT will sell your management the tools you are required to use every day.
That’s more of a free software mentality. Open source is just open source; Microsoft has some open source software, they use some open source software, but they are in the business of selling proprietary software and free software as Stallman defined it is antithetical to that.

That would wouldn't change a thing even it happens. No one except Microsoft is going to be expert on 50 million lines of windows code and contribute meaningfully to it. Add to that contributor's licensing agreement, community behavior, sheer capacity to make API changes and get it accepted. It will be impossible to create alternate certified Windows distribution even if all source code was available.
