You as a user may work for a company which feels it can't afford the risk of GPL-licensed code getting into their products, and may thus forbid you working on GPL-licensed code while you're working for them.

Or somewhat lighter but no less bad is the case where your workload could be eased or better results achieved by incorporating BSD-licensed software into your company's product where your company feels it couldn't allow GPL-licensed software.

These cases show the GPL is better for hobbyists than working people.

Then there's the fact that the GPL doesn't restrict the authors of the software. Some companies release under the GPL to get fixes, features, and kudos from the open source community without making life too easy for their competitors.

Overall the GPL does do some good, but it's certainly not freely giving to the world in the way MIT and BSD licenses do.
