Not all companies have that policy (Score 2, Interesting)

The company that I work for has never had that policy. We have products for AIX, Linux and Solaris; while we charge per processor, it's never been our policy to charge per core. We had to tweak things recently for our Linux products to understand about multi-core processors. Before we did that, we'd issue the users licenses that would be double the number of processors if they were using hyperthreading.
