Linux is nothing without the hundreds of commercial programmers that have helped to improve it. Too bad for those companies paying them to do it, like IBM, Red Hat and Novell who have seen their stock tank as a result.
Horsefeathers. All the tech stocks have tanked. That has nothing to do with open source. It has to do with tech being way over-hyped and over-sold in the 1990's. On balance, the companies who have committed to open source are doing no worse than their proprietary-only counterparts.
