Technically true, GPL, LGPL, etc are all licenses. But they are licenses that require fairly limited thought to use the software (modifying the software or borrowing its code is a slightly different story, but those aren't even options in most cases in the closed source world). Compare that to major enterprise software where everytime you need to install it on a different machine, move it from one machine to another, etc can require careful licensing management. At one corporation I worked for, licensing tracking and management was a major portion of the work of one fairly senior person.
