So, to the OP: If you release the code under the GPL, then anyone is free to take and use it and do anything in the world they want with it. However, should they choose to distribute it to anyone else, then any changes they make to it must be provided to this "anyone else" according to the same terms. So, someone who takes your code and say, adds a module to it-- that module can't be in any license but the GPL (or rather, no license more restrictive then the GPL). Notably, this code can't end up in any closed or proprietary product. If you release the code under a "permissive" license, like MIT or the 3-clause BSD, you're basically giving everyone in the world free reign to do -- anything they want with it, without any sort of "but's". They just can't say you endorsed it generally, and can't sue you for it, and they can't claim it was theirs (though they aren't required to admit it was yours, either). Someone can take it, rename it, and re-release it as a closed-source program if they want. Or, someone could incorporate it into any number of projects that are open source and not GPL-- whereas GPL code can't ever be incorporated into non-GPL code, without the whole codebase becoming GPL. Notably, Python has a permissive license, albeit one which is very, very wordy. What you decide on is up to you. Me, I'm very strongly in the MIT camp. I consider what I may release as a sort of donation, and don't expect anything of anyone-- and don't even mind if someone makes money off of it without being a good sport. "Freedom" and software have nothing to do with anything to me. I do open source because I think its an excellent way to get technically excellent products. The decision of which camp you find yourself is up to you. :) (Then there's others, like Artistic, the Apache, and on and on) --S
