This article about SilverStripe "giving away their product" completely misses the point of open source. I think that like most of the general public here in NZ (perhaps worldwide?), the author understands that "open source is free" (like free beer), but misses the point that SilverStripe's software, and open source in general, is not free because it costs nothing, but because the code that is written to create the software, is open for anyone to use, look at, modify, enhance, learn from, redistribute, sell, print out and use as toilet paper, or glorify in a nice picture frame above their mantlepiece. Because the code has been freed from the restrictions typical of commercial software licensing.
