That post's conclusions aren't really universal for tech. Yes, many companies take and don't give a lot back. But some big names definitely contribute (Google, Yahoo, Apple to an extent...). There is also plenty of innovation done by people in their spare time. So much so, that software patents are a hot issue: who wants to be sued for making something cool, only to find out that Microsoft claimed it a year ago? It's also funny they don't mention Microsoft or other companies whose actions alone were enough to freeze innovation in several areas. If your goal is to make money, you can't compete with the establishment...you have to move on.
