Can you please explain further what leads you to the Linux line you posted? How it relates to today's news?
Serious question, I am not trying to be funny, may be I should read again but don't see the actual connection to something MS said today.
It's not in the statement from Microsoft I quoted.
But many times in the past Microsoft has alleged that Linux/GNU violates in excess of 200 of its software patents. And although the company has waffled around acting upon it (and refused to say exactly what
those patents are) no person in a position of authority at Microsoft has ever ruled out a future lawsuit or series of lawsuits. At this point in time, Microsoft seems to have contented itself with spreading enough FUD that many companies (and a few big Linux distros such as Redhat and Suse) have purchased licenses from Microsoft for supposedly infringing their IP. Unfortunately, those licenses are (by contractual agreement) a secret between Microsoft and those who signed them. So nobody in the broader FOSS community knows what the specific claimed IP violations are, or is able to re-code or change things in order to be non-infringing. Assuming they actually are. Cute move huh? It's basically saying: "You're infringing - but we're not going to do anything to let you know what or where."
When Linux began to look like it had a shot at becoming the next dominant desktop OS, Microsoft upped it's posturing and threatening. Including threatening corporations that adopted Linux. It's true that once Windows 7 became the success it became, and some major players in the FOSS community caved in and bought questionable licenses, Microsoft ramped their threats back down. But again. they never ruled out legal action in the future.
From Microsoft's past rhetoric and behavior, I suspect if they get a lot of pushback on where Windows 10 seems to be going - and Linux again starts looking like a good replacement - they'll start up their legal bullying and FUD machine again. Or possibly invoke the nuclear option and actually file a lawsuit against someone. Most likely Linux (i.e. the kernal) itself, which they claim has something like 65 infringing pieces in it.
Hope that clarifies. It's a long story. And it's been going on for the last 10 or so years. This
is an older article that gets into the nitty -gritty of the thing. It'll give you some background as to what it's all about.
