2007 leak gets a takedown notice

A DMCA from Valve has been issued against the most popular repo containing the 2007 leak. The repo had been there for more than a decade.

Some people have said it could be a troll, but it's impossible to say at the moment.

If this is legitimate, I respect the decision, but I hope we're not just going to be left in the dark to the benefit of seemingly no one. The 2007 leak has been the only reasonable basis for many mods and was how many of us learned important things about how the engine works. I hope this means we'll be getting official (and updated) SDKs for more games, and that Valve will reconsider what they ship in the SDK(s), because what's currently shipped is only a fraction of the engine, and there seems to be no rhyme or reason as to what gets in and what doesn't.
