Cellular telephony seems to be the biggest network implementation (bigger than the Internet in means of user base) that has been surprisingly closed to inspection and experimentation despite its age. Lately, I've started actively getting informed about GSM network protocols and their free implementations such as OpenBTS and OpenBSC.

Please don’t take this post the wrong way just because of the title. I love the FSF. However, based on my observations, it has made some major mistakes that have ended up leading fewer people to freedom. Allow me to elaborate.
