It's certainly one perspective. For some types of software it may make sense. I generally release software under the BSD license. My goal is to allow the widest possible use with as few legal restrictions as possible. I have no moral objection to companies using my code, building on it and not contributing back, if that is what they want to do. I like seeing my stuff used and benefiting the maximum number of people. So far, everyone who had used my code has contributed back. Most people don't want to maintain forks and their own patches. My stuff isn't that strategic I guess. Just useful.
