content: This is just my paranoia, but Microsoft is known to behave like a patent troll, even threatening companies and getting extortion payments before they have disclosed exactly what patents they think are being infringed.  Imagine 5 years from now, Microsoft has their own Linux distribution that they give a way "free" but charge a licensing fee for open source Linux (any other distro) because of patent infringement (like how there is a Microsoft Android Tax).
