The business case for open sourcing dev tooling is that more developers will use them and build on them and that brings more people to your platforms.

Sure. Any proof at all for that? I mean it's the obvious answer, but generally in business people who don't pay for things tend not to pay for things. In fact, in the enterprise having a big budget is the way you keep your corporate power. Free stuff isn't a way to keep your budget high.

Again, I would like to agree with your thinking. I just don't think the real world backs it up.
