I am not sure how that generalization comes about since there is a large mixture of opinions, and canon can be both an asset and a restriction, as continuity can come back and bite you. And this isn't restricted to Trek as there are a number of shows and movies that rely upon fast and loose continuity or the audience not paying attention to make it work.People here are generally supportive of the Abramsverse which eschews Prime canon in favor of a rebooted reality with the freedoms of creating a completely new story because Prime canon, as Daystrom put it, "simply got in the way." Prime canon is that ensign in M5's bug zapper. I've called bullshit on such restrictions of canon when you have a whole universe to play with, but here we are.
I personally think that the Abramsverse presents opportunities to explore the familiar without previously established restrictions on technology or outcome. But, the couldn't even get that right with the USS Kelvin and its uniforms, phasers, and design
