They've agreed to deprecate the program but once the post was out and got terrible feedback, they realized that deprecating a developer program is not the best idea for something like GitHub, let alone announcing it as such. So instead of admitting they've made a mistake in deprecating the program, they're blaming the messenger and pretending it never happened. They went as far as getting the archive.org pages blacklisted/hidden apparently, which shows somewhat clearly the mindset involved.

That is a very reasonable ask. I'll be doing a post-mortem, and talking to all the individuals involved - and will do a followup post on it on the same blog. Please stay tuned. And, again, our sincere apologies.
