I'd be interested to see that repo since one of the commits to Automatic's github is Anlatan's code while a second commit changes function names and tweaks the code slightly in an apparent effort to disguise it's origin. Most of the discussion about this has been on 4chan where the amounts of misinformation has been staggering before it pretty much devolved into "it doesn't matter if their code was taken, it should have been open source anyway".
As you can see, that repo from 2 years ago even originates the "# attention, what we cannot get enough of" comment and is an exact 1:1 match to Automatics commit, while the one from NovelAI even has a small change in the if clause that Automatic doesn't have.
The code that was taken from Anlatan is actually this:

But that same GitHub issue also shows code from the lucidrains repo (the picture you've linked there) and people have latched onto it saying nothing was taken when the picture I linked is right above it containing code that doesn't exist outside the leaked code and Automatic's fork.
