Yeah, I'm not saying it's true BoS but it seems a little closer to the way they were originally depicted. They went too far w/ that angle. I prefer a xenophobic, elitist BoS to a group of sellf-less do-gooders. They were always kind of pricks-- but they turned them into straight-up assholes. Not to mention, the FO4 brotherhood is the polar opposite of secretive, isolationist, tech-hoarders. They leave piles of dead Paladins, power armor, and laser weapons all over the Commonwealth.
The portrayal of the Brotherhood in every Fallout game is totally legitimate, even Lyon's vision. This is not a self-selecting society: people are born into it, and people vary widely in how they approach the world. Maxon and Lyons have both abandoned the Codex, as had the midwestern chapter, because it simply doesn't work. The midwestern Brotherhood is even less justified in Tactics because there had been no war with the NCR yet.
The decision to make the Brotherhood into a fascist occupation force was a good move on Bethesda's part, not because 'that's how the Brotherhood is supposed to be,' but because it's an insightful commentary on the nature of a leader's vision versus institutional norms. It's the smartest thing in Fallout 4, which isn't saying a whole lot, but in a game as good as Fallout New Vegas it would be the smartest thing in it.
