The difference with Hello Games and CIG is that CIG hasn't had a problem to correct expectations (even if a little late), while Hello Games kept the expectations high and wouldn't even retract on its statements after release of the game.
Of course they haven't had that problem, because they haven't delivered a game. But one day Star Citizen will either reach what Roberts considers the MVP, or else the project will collapse, but either way there will be a point at which CIG has to face up to failing to deliver on the countless unrealistic expectations of its fans. That's not even a criticism of CIG, because the fans are also projecting their own delusional notions of the BDSSE onto the game, regardless of what Roberts promises, just like they did with NMS. Which is why, even if they did manage to deliver on their promises, they wouldn't be able to satisfy expectations. The backlash is inevitable.
But another difference compared with NMS is that CIG is actively pumping out hours of propaganda. Sean Murray is on the record as having made a handful of comments about a couple of features which weren't in the final game, and there are a handful of points you can make by picking apart their otherwise quite representative trailers, but beyond that they did nothing to "keep expectations high", or at least not as stratospheric as they were. CIG is actively complicit in whipping up the hype for SC, with Roberts himself repeatedly describing all sorts of fanciful mechanics that they'll never deliver. That will come back to bite him, big time. It already has on countless occasions (Star Marine, for example).
