Fascinating insight from Tim O'Reilly in InfoWorld. He says open source licensing isn't working as planned, as the GNU license contemplates sharing of proprietary extensions for software that is redistributed.&. Instead what is happening is use of open source in web services such as Amazon, Google, etc. No need to share as no redistribution. Hence able to build proprietary extensions. More importantly, he suggests that the whole thrust of using Linux to defeat Windows is fighting the last war. Gates' insight was that software would become more important than hardware. Value would shift from computers to software. He was right. Now software is being commoditized. Value is shifting from software to data services like eBay, Amazon, Google. Someday Bill will wake up and see that his real threat came from that other tech company down the street in Seattle, Amazon.
