What does ESR stand for in this context?

[lisasays]

Some guy who went around claiming to be responsible for all kinds of stuff, when in fact he just didn't do all that much.

Eric S. Raymond I assume. I’m not sure what the reference is about. Maybe some internet lore I missed.

Yes, Eric S Raymond. He was well known in the late 90s / early 00s for taking credit for all kinds of things that he did not really contribute to.

I believe that he turned 100% conspiracy theorist in recent years. He famously blames Alan Turing for his own judicial punishment and suicide.
