It's not a matter of "it's wrong to use X". It's a matter of "I don't want to spend my time working in Windows and dealing with all of the headaches and banging my head against a wall with the differing OS paradigms."
True story. At my previous company, it wasn't made clear during the interview that Windows was the ONLY thing allowed on the network. Despite the fact that all of the servers were running Linux (this was a major financial institution), we were forced to use Windows XPSP3 and we couldn't even use VMware (that changed a month or so after I got there luckily).
Neglecting to mention that was a CONSCIOUS decision by the people doing the hiring because it cost them employees. Not only did it cost them employees who turned down the job based on that fact, they had people LEAVE once they found out about it (developers and operations folks alike).
Talented and skilled people can get a job anywhere. They don't have to put up with stupid bullshit illogicals like "You have to use Windows even though we trust the financial records of customers of EVERY MAJOR CREDIT CARD COMPANY to live on and be processed by Linux servers".
