AFAIK this is THE reason for GPL. So that you either release your code and contribute to open source or suffer from slower access methods.

The BSDs doesn't ship with bash and their wordexp shelling out to /bin/sh doesn't suffer, so I don't see how this is a reason for the GPL.

Probably I've written it not clearly enough: "Reason for GPL not allowing you to use code in your own programs, but allowing use through exec: you either release your code and contribute to open source or suffer from slower access methods."

ahh, ok; that's clearer
