The part about it being as much a MMO as CoD is already in your Wall of Text, the second KS post. His exact words were "I don't see this as an MMO in the traditional sense, unless you think of Call of Duty as an MMO."
About he not wanting to call it a MMO early on, well, besides that very post hinting at it, and the Kickstart page not using that term even once, I remember hearing it in old video interviews from the KS era. The "I don't see it as an MMO in the traditional sense" line came out quite a few times before fans managed to finally convince DB that Elite Dangerous, as pitched, would qualify as an actual MMO.
There are other interesting things to find in those old interviews. For example, just from the Gary Whitta interview with David Braben and Chris Roberts, you have:
(Part 1) (Part 2) (Part 3) (Part 4)
As reference for the following quote, here is Chris Roberts speaking about the Star Citizen equivalent of this thread (part 3, 5:30):
"And the key is kind of what David alluded to, which I think it's a debate that David has with his community and it's a debate I have with my community because there is definitely this whole sort of PvP and PvE sort of factions that go on and they're all pretty rabid. And so I think, and I think David also believes that you can sort of create a game that can cater to both sets of players and it will be okay. But it certainly is, that is, I would say if I were going to give you a touchpaper to set up a fight with your community that's the one to do it."
The immediate follow up by DB about PvE groups (part 3, 6:01):
"Well, the discussions have come up already. We have this concept of groups where you can join a group which doesn't allow or does allow it on the user choice."
Or this about the kind of game DB would want to play (part 3, 7:09):
"You know, so what I would I want from a game? I want to be able to play a great game without being griefed by teenagers, but having said that I do want there to be a feeling of risk out there."
Also this about what player interaction in ED was supposed to be about (part 3, 2:06):
"And so, I don’t mean necessarily every ship should be a player because then you get into a frame of mind that you can’t kill anything without really upsetting someone. I mean with Elite: Dangerous it’s still…a lot of the ships you encounter won’t be real players but we will call out, of the ships that you meet, who is a real player. We have a way of distinguishing them within the game. They’re actually part of this group of pilots that you’re part of and it will call out, above them say. Essentially what it means is “this is a real player,” but in the game fabric: “so this is a group who a member of the same organization as you.” We…you know, in other words we, we don’t want this game to be all about player vs. player kills, but the point is it encourages a lot of cooperation. And, it will be possible to do player vs. player kills if that’s what people want to do. "
