Ask HN: What is Microsoft's endgame in open-source?

I was just reading, http://www.techrepublic.com/article/microsoft-shows-vmware-and-oracle-how-to-get-real-about-open-source/.

I cannot still figure out what is Microsoft's endgame with open-source. I really love VSCode, but I am worried that I am just a pawn for the famous [Embrace, extend, and extinguish](http://en.wikipedia.org/wiki/Embrace,_extend,_and_extinguish) ploy and its just [MSJVM](https://en.wikipedia.org/wiki/Microsoft_Java_Virtual_Machine), again.

As a victim of ie6 apocalypse as a developer and still fighting to keep my win7 machine at work as I just hate win10. I believe that Nadella is just a decoy & I am just waiting for Baller to jump out screaming "gotcha!" & go on one of his crazy rants.
