Leaving aside that the vast majority of the so-called "bullshit" in that video is purely subjective (e.g. "real" dinosaurs, "will you get bored") or trivial (e.g. a creature pushes aside trees), it's clear that nearly all the player grief stems from Murray's responses to questions about multiplayer - and the video shows those responses entirely out of all context.
I watched a lot of the original interviews at the time, and while Murray did on some occasions answer with tentative "yes" responses to questions like "can you play with your friends" and "can you grief other players ("kinda") - questions that could be ambiguously interpreted, but I agree he should certainly have answered differently - he also spent considerable time downplaying any suggestion of multiplayer, saying it's not that sort of game, it's not about playing with others, it's not designed for that, and anyway there'd be virtually zero chance of meeting other players anyway. You saw none of that in the video, which was obviously designed to pick over everything he said in hindsight and show it in the worst light.
I get that some people really wanted multiplayer in there, but that was never claimed on any marketing material, and Murray invariably tried to steer away from those questions if it came up in an interview. Personally I never thought for a moment that it was a multiplayer game in any sense, and was surprised by the backlash from people that wanted to think that it did. The reviews were certainly very clear that it was solo only.
