I agree with some of your sentiment, but you shouldn't blame the academics. There are many academics who are no longer allowed to use things they invented them because the patent goes to the university. As a well-known example, John Pople wrote a program called Gaussian while at Carnegie Mellon. Carnegie Mellon licensed the program to Gaussian Inc. When John Pople moved to Northwestern, he was banned from using the program he wrote, as was all of Northwestern University. Before the passage of Bayh-Dole, Gaussian was given out for free by Carnegie Mellon. Once Bayh-Dole gave them clear rights in the code, everything changed.
