Trust me, guys, the 'difference' is in the eyes of Trekkies alone.
This. The JJprise is familiar enough that people who left Trek or only had a passing acquaintance with the franchise still came to watch the movie.
And this is relevant why?
Because the OP asked why the very simple question of the Enterprise had to be changed. Whether it's aesthetics or whether it's for profit, it still boils down to appeal, and clearly that appeal worked...
Look back and you'll see that I was asking why it's relevant that casual ticket-buyers allegedly "don't care," since they're not the people participating in this discussion.
(Although FWIW, I've found myself discussing the redesign with more than one of them, and generally encountered something less than enthusiasm, even among folks who liked the movie).
For those of us who do notice and care about the details, the fact that it made money is utterly irrelevant. We're talking about the art side of things, not the commerce side.
That's nothing new for the franchise, and honestly only matters to a small group of people.
Same puzzlement again, since we
are that small group of people. How is it relevant to a discussion of
any controversy to say "hey, those folks over there don't seem to be bothered by it"? If the concerns and standards of casual moviegoers were the standard for discussion, 99.5% of what's discussed on these forums should be tossed right out.
If they put the "elegant, classy" Enterprise back on the screen... well, they might just as well have called it Star Trek Nemesis II because it would've been a failure.
I've seen this argued before, but no one ever advances any actual evidence. The counter-evidence, OTOH, is widely available. There are numerous sophisticated, detailed, and "elegant and classy" computer redesigns of the Enterprise that have been shared on these very boards, many (indeed most) of which honor and respect the design aesthetic of the original far more than what we saw in this film.
Hell, the design of Robau's U.S.S. Kelvin in this movie fits the design aesthetic of the original (single nacelle notwithstanding) far more than the NuEnterprise, and no one has said it looked out of place on screen.
The only problem IMHO is that this Enterprise isn't nearly as beautiful as previous versions. The Refit doesn't get nearly as much negativity from fans of TOS because it was a more successful update - and I mean that taking into account the fanatics who are unhappy with anything different.
Bingo. As I've already said, the concept of a design update wasn't necessarily a bad idea in the abstract.
This particular design update, however, left a great deal to be desired.
