You got that right...can you say, "hidden agenda"?
Personally, I have nothing against any OS. I use Win2K, BeatrIX, Mepis and Vector Linux at work, Knoppix/Win XP dual boot on one of my home computers, Mepis/Win98 in Win4Lin on my laptop, and another home box uses Mepis exclusively. I think more is better, and if I could install a Mac OS on my box and triple boot, I would!
Every OS has its advantages and disadvantages. Windows is nice because of the wide range of apps available for it. Once you got it properly locked down, it's a nice system. And of course, Linux is rock solid...the computers at work often go for well over 50 days between reboots, and no spyware or viruses.
As for usability and user-friendliness, I couldn't give the nod to either. Configuring Linux after installation isn't any harder than setting up spyware/adware software and antivirus programs, or removing bad registry entries.
I just think anyone who comes down firmly on one side TO THE EXCLUSION of all others is probably operating with motives that we don't know about.
