Yes using permissive license allows businesses to take unfair advantage of the work done by the community for their own profit without contributing anything, but it's explicit in the license terms. When you go with *GPL + CLA, it's more subtle: bad things can happen, but pinky promises are made that won't be the case. We've seen that movie before of course. As a community contributor, I may not want my contributions to be used to enrich a corporation that doesn't give back to the commons.
