Why is everyone so surprised that Microsoft bundled a language that Microsoft built into a piece of software that Microsoft built? This says nothing about TypeScript's future among non-.NET developers.
And this is why TypeScript is 1-2% of the market? Check out GitHub and the rest of the community outside of your workplace or whatever place you are seeing this trend, because the numbers are not showing this. Even search terms of google trends http://www.google.com/trends/explore#q=%2Fm%2F02p97%2C%20typ... shows the term JS is more popular than TypeScript. Also look at twitter and what the great developers of JS are doing; not TS. TypeScript has now tied you to an IDE on some OS (Windows) even if developing on a Unix based server. When you can simply edit JS from a half-gig box using vi if you needed, and do some awesome code. I just don't buy the idea no matter how much Microsoft throws at it, same with dart or any company backed layer over JS.
