Is anyone making money by selling GPL licenses in the real world? I mean, just from the license sales, not from services, etc., attached to the software?

As soon as you sold your first GPL license, your competitive advantage would be reduced to nothing because the person you sold it to could turn around and distribute it for any price, including for free.

Are any businesses actually doing this?

(I guess if there are they wouldn't want us to know, lest we track down one of their customers and get the software from them for free!)
