I don't have a problem with the author wanting to charge for it as it is his software afterall, but I really wish more software vendors would follow Redhat's model of charging for the stable and supported version of their software, and giving away the bleeding edge 'Fedora' version for free.
As a techie, I love getting my hands on the new and most innovative stuff; I'm okay with breakage.
As an IT manager, I just want the stuff to work and be stable, with well planned upgrades.
I'm not sure where software authors got the idea that charging for their newest and buggiest features was a good idea. When I'm buying software, I am buying robustness and stability. I just want it work.
