I doubt that is the case. With employment at record highs and good jobs not available I don't think people would rather sit idle than take up a job in .Net. The article can also be rephrased as "Demand for .Net developers surges." Of course it won't be as newsworthy then :)
Sure, there's always going to be a mountain of job applicants for each position, it doesn't mean they can do the job. Finding qualified .NET developers is the real challenge, someone who can architect and build a functional system.
These are the very type of people who are bailing on the platform.
