The first paragraph is just silly:
"After years of trying to cut off Linux growth as a desktop platform on x86 and x64 PCs, Microsoft may have actually figured out a way to stop Linux deployments on client PCs dead in their tracks."
I'm quite certain Microsoft has (A) not put any significant effort into cutting off growth as a desktop platform, and (B) If they had, they were almost completely successful, and characterizing it as "trying" implies that they had limited success.
