For whatever faults MSFT has today, any sort of antipathy or guile towards OSS or Linux is not one among them. Credit where credit is due. Too many are stuck reliving past glories.
If you want an actual OSS bogeyman, you need only direct your attention to Oracle. Too many transferred their goodwill towards Sun to a company has, among other things, tried to claim Java’s APIs as their own intellectual property. That’s a company that still merits this kind of hand-wringing.
