As a former antivirus company employee, I find such a call irresponsible, poorly timed and an affront to the community. On so many levels, such a call is, quite frankly, utterly wrong. Linux does not need any virus to disrupt end-users lives. Linux does not need any association with anyone writing viruses. Linux does not need anyone to call for people to write viruses to do such a thing to become an effective desktop.
Linux is effective today as a desktop no matter what anyone would have you believe. I have been using it quite effectively for some time now, and although I dual-boot for games, I dont miss Windows at all. What Linux needs to succeed is more hardware manufacturer uptake for pre-loading, more hardware manufacturer driver and associated application support and better marketing to the end-user."
