Here is yet another post arguing that open source software introduces a pricing race to zero that threatens the entire software industry, especially commercial efforts within it. It's from Gene Quinn, a patent attorney, writing for IP Watchdog. Dana Blankenhorn has
an interesting reaction post up, in which he argues that open source doesn't drive all costs to zero, but that costs become shared. I agree with Blankenhorn, but there are several other fundamental problems with Quinn's argument.
