>Microsoft is far more receptive to the needs of the open source community.

They are, but not for this reason. Microsoft doesn't even support IE9 anymore, so there's not really any reason for any open-sourced project to do so.

I apologize for not being more clear. I was thinking about the flexbox more than the IE9 deprecation. The jQuery story was only to reinforce the idea that open source projects are "at the negotiating table".

There is a footnote on that page for IE11 (I believe still supported by Microsoft) that says:

"Partial support is due to large amount of bugs present (see known issues)".
