Why buy in to a tool you're not at liberty to hack to fit your needs?
I can see how I'd do it if I didn't value my needs much, or if I had a very good feeling about being able to have somebody else fix my needs for me, say, as was the case between Linux and BitKeeper, but failing both, which I'd say Pike does, I don't see why the license isn't a show stopper.
Hm. Except if I'd firmly believe that I wouldn't ever have any needs that aren't already fixed by someone else by the time I get them. I have never ever had that happen to me in online resources, though.
