Non sequitur?

I don't understand. What does Google or the OIN have to do with Linux being protected from Microsoft's patent claims?

If the OIN own some of the patents MS claim they own, or if the OIN own patents which Microsoft are using without permission and could thus sue MS in retaliation, then that would connect the two things, but nothing like that seem to be mentioned. Just that Google is using an OIN licence or something, and the OIN has some large members who own some patents. So what? Did my brain skip over a paragraph or am I missing something or what?

I know MS haven't said what the patents actually are, and to me that makes their claim more FUD than anything else so far, so I'm certainly not siding with MS on this issue, I just don't see the connection this article, and its headline in particular, seems to be drawing.
