100% wrong.
No matter what people were told they'd still be complaining. Because the people making the most noise are the ones who will complain about everything all the time. Let's be clear: this is the prime timeline, they're making a visual retcon. END OF STORY.
Some would complain but it wouldn't be over canon. It would be over the premise if they didn't like it. It would be like how with "Enterprise" the main complaint was that people didn't want a prequel since we would know how the future would turn out.
I supose their was some about the tech and uniforms but that never seemed to be the main complaint . Actually letting Berman and Braga have another go was most likely the main one and then after that was the setting. I think the only real canon issue was the idea of having a Enterprise that existed we had never heard about.
Also a visual retcon is okay just not in the time period they choose. Even people who talk about a more retro/future look were also calling for a visual retcon just one that feels more natural. It' also why The difference between "TOS" and "TNG" doesn't have this issue. If "TNG" had been set 10 years after "TOS" it would be completely unbelievable. Nobody would buy into it being in the same universe. People would have just called it a remake. Nobody wonders if the old "Battlestar Galatica" and the new one were in the same universe even if they would sometimes use some old stuff like Cylons and ships as kind of nods to the old show.

 so any discontinuity is made with concious choice, updating the bible and so forth for future showrunners, The look of the Klingons are an example of this. There look changes so much over time due to the evolution of special effects, make-up and so forth, the same with the settings, Camera techniques, ship designs, etc.
