I'll share back too if it I have some improvement (I am going to test in on my own site first).
Greed is actually a very poor reason for not sharing back. It actually costs more money to maintain a forked code base than contributing the change back and getting it maintained by everyone. It is also fairly stupid to hide what software you are using from a recruitment point of view.
I prefer the BSD / MIT licenses because the sharing occurs on my schedule, less stress, and less friction. I like doing things because it is right and not because I have a lawyer at my door.
