Once again a supposed fan of FLOSS trumpets an attack-piece listing the many flaws of GNU/Linux while completely getting it wrong. The first item, hardware support, for instance, is clearly wrong. GNU/Linux supports far more hardware out of the box than that other OS. That you can move a disc-image from one random machine to another and get it working instantly is proof of that. That’s almost impossible with that other OS.
So, GNU/Linux is the worst system for IT imaginable, except for all the others… GNU/Linux is not perfect but it has very few problems beyond exclusion from retail shelves, a deliberate plot by M$’s sales-droids.
