Is this guy genuinely suggesting that people fell in "love" with distributed version control solely because of GitHub? I don't feel old enough to be telling this author to get off my lawn. I mean, GitHub is great and all, but it does not represent the sum whole of all the commits in this world.
Granted, does anyone know the timelines of when DVCS took off (as opposed to launched)? Mercurial and Git were both released a good 3 years before GitHub was launched.
Okay, I looked up more about DVCS. Wikipedia article's history section on it:
History
Closed source DVCS systems such as Sun WorkShop TeamWare were widely used in enterprise settings in the 1990s and inspired BitKeeper (1998), one of the first open systems. BitKeeper went on to serve in the early development of the Linux kernel.
First generation open-source DVCS systems include Arch and Monotone. The second generation was initiated by the arrival of Darcs, followed by a host of others.
When the publishers of BitKeeper decided in 2005 to restrict the program's licensing,[5] free alternatives Bazaar, Git, and Mercurial followed not long after.
