With the open source licenses that allow redistribution of modified code, how do you keep someone unaffiliated with the Python community from creating his or her own version of python, and declaring it to be Python 2.6, or maybe Python 2.7 without any approval of anyone at the PSF? Maybe their code is terrible, and not even compatible with the rest of Python! How can the PSF, for example, maintain the quality and coheren of new code contributed to be part of Python, or derivative works that claim to be some future version of Python? If licensees can redisribute as they like, isn't this a huge problem? Is this dealt with be restricting use of the Python trademarks? Just curious..
