See, this strikes me as puzzling. There is a fundamental difference between saying "don't contradict things we already know," and saying "don't tell us anything new that we don't know, because we know everything."
I don't see any difference there.
Is this not the same thread where people are insisting that Discovery MUST be a reboot because their holographic technology is too advanced? The obvious implication: They couldn't have that kind of technology, because we would have known about it!
People have insisted that Spock was the only Vulcan in Starfleet. There couldn't be other Vulcans, because we would have known about it!
People have insisted that the Enterprise was the biggest starship in the fleet. There couldn't have been bigger starships, because we would have known about them!
People have insisted that the Klingon War violates canon. There couldn't have been a Klingon War during the Pike era, because we would have known about it!
People STILL insist that the spore drive renders the entire premise of DS9 and Voyager moot. There couldn't have been a spore drive, because the crew of Voyager surely would have known about it!
New information seems to contradict the old information
if you assume the old information is as complete as it could possibly get. The gaps in our knowledge about the 23rd century, however, are rather enormous and there's ALOT of room to fill there. The producers haven't assured us anything except that the new information they're showing us won't actually CONTRADICT what we already know. Beyond that, however, all bets are off.
I can't see why the producers would imagine it's a widespread thing.
IIRC, this statement was originally made at one of the ComicCon panels, so it's not hard to guess where they got that impression.
Or if that doesn't work, just look back through the complaints here on this forum. They all have the same basic theme: "Discovery can't be prime because it's too different from what we were expecting!" All of which implies that we knew enough about the 23rd century to know what to expect in the first place.
But this is not what people are concerned about.It's not what they're complaining about. It's missing the point.
I think you can only speak for yourself in this case. A fair number of people are indeed complaining about exactly this, some right here in this thread.
Although, you're right, they are definitely missing the point.
That's kind of a bait-and-switch. That's going ahead and changing things we really do know, and then patting us on the head and making an excuse for it by saying the stuff we knew wasn't "important."
And again, you can only speak for yourself as to what you think is and isn't important for the majority of fans. But if anyone has final say over what matters and what doesn't, it would be the people who actually made the show in the first place, not the audience. We can misinterpret what we're seeing and read too much in to a particular choice, but the producers know what those choices mean and why they were made in the first place.
