I understand. The value I get for the additional cost is that my code is secure - the server is in my own network + code is encrypted.
Nice article Jason! Though I agree that github "doesn't have a history of acting in bad faith," I would not employ a "wait-and-see perspective." I was looking to spin up my own git server but found that someone had already done all the hard work. I have been using http://gitstorage.com/ comfortably for a while now; definitely a viable alternative.
