The issue was not exclusion, nor bashing. The code has been accepted by a driver maintainer, and there were surprisingly few critical undertone mails on lkml, however legitimate (namely, adherence to the Linux coding conventions).

What is not pointless is honesty, and not even Linus[1] can say, that the code drop was honest. Microsoft should have said: somebody found us in violation of the license we think is important [the licensing legalese itself, not the GPL], and this is how we fixed it. Sorry for our mistake, we do our best. This is not what happened: instead it was sold as an act of benevolence. Voleurs.

You cannot blame people for hating dishonest legal persons.

[1] should take a long look in the mirror and ask themselves why they are being so hypocritical.
