To what extent did Eliezer Yudkowsky invent the Effective Altruist movement?

Hurling ordure at the TREACLES, especially those closely related to LessWrong.
AI-Industrial-Complex grift is fine as long as it sufficiently relates to the AI doom from the TREACLES. (Though TechTakes may be more suitable.)
This is sneer club, not debate club. Unless it's amusing debate.
[Especially don't debate the race scientists, if any sneak in - we ban and delete them as unsuitable for the server.]
EA as a movement was a combination of a few different groups (This account says Giving what we can/80000 hours, Givewell, and yudkowsky's MIRI). However, the main source of early influx of people was the rationalist movement, as Yud had heavily promoted EA-style ideas in the sequences.
So if you look at surveys, right now a a relatively small percentage (like 15%) of EA's first heard about it through lesswrong or SSC. But back in 2014, and earlier, Lesswrong was the number one onroad into the movement (like 30%) . (I'm sure a bunch of the other answers may have heard about it from rationalist friends as well). I think it would have been even more if you go back earlier.
Nowadays, most of the recruiting is independent from the rationalists, so you have a bunch of people coming in and being like, what's with all the weird shit? However they still adopt a ton of rationalist ideas and language, and the EA forum is run by the same people as Lesswrong. It leads to some tension: someone wrote a post saying that "yudkowsky is frequently confidently, egregiousl wrong", and it was somewhat upvoted on EA forum but massively downvoted on Lesswrong.
