I think this is overstated. Transparency is a philosophy of design, to be sure, based on the notion that artists are musicians and their producers, not the designers of playback equipment. And it is a philosophy that most manufacturers at all levels claim to pursue.
The limitations of vinyl are something we accept, and we achieve some degree of transparency partly because those limitations were understood by the artists (musicians and producers) when they created the art. They were compensating for the playback limitations of the day. But the result was all over the place, simply because they were using wacky stuff in their studios, and those limitations were widely variable and unpredictable for any given listener.
I have to say that I distrust any argument based on the phrase "that's how humanity/civilization works", simply because everyone has their own opinion of that, deeply rooted as they are in biases and metaphysics more than in anything demonstrable or predictable. I think we can make those statements regarding relatively microscopic effects only after conducting considerable behavioral research. Yes, it would appear that humans are tribal, but I do not accept that all fundamentalists are the same.
Transparency seems to me the lack of downstream coloration, and many who apparently favor coloration (as evidenced by their choices and their resistance to measurements of transparency) nevertheless claim to favor transparency. So, what camp are they in? I see a difference between motive and intent--their stated motive is transparency but their intent, derived from any potential consequence of their actions, is something other than transparency. But what? Before you can identify camps, the camp has to have a reason to be a camp. If most are claiming transparency as an objective (and it would seem so as I read specifications for products used by just about everyone), then I'm not seeing transparency as a camp. I'm seeing the demonstration of transparency using measurements as a camp, versus those who think they can judge transparency without measurements, or those who believe that transparency and preference for a certain coloration are the same. All three of those possibilities can and have been explored with measurements, either electronic measurement of equipment or preference measurement using properly controlled testing.
