In a stunning reversal of the usual thread dynamics, it seems to me that the most unreasonable post in this thread is the OP's, and that the ensuing discussion has been almost exclusively fervent but civil. (This observation isn't directly germane to MG, but it struck me forcibly as I scrolled through.)
You really could substitute exactly this discussion for a billion identical debates that don't really get anywhere on virtually any cultural topic---undergraduate syllabi, high-concept productions of Shakespeare or the Ring Cycle, free jazz, modern architecture, 20th century "serious" music, modern art, modern art criticism, lit crit., ad nauseum.
Whatever the discipline you tend to end up with those in the field feeling absolutely, passionately that a given trend is "wrong,"---fundamentally, morally even. Dishonest, a breach of faith with the past, and destructive of the efforts of others, displacing work of greater virtue and less flash, with dazzling meretricious crap. Etc.
But everything shakes out in the end. If you don't like it, don't eat it. (Or listen to it, or read it, or watch it, etc.)
In some fields you could at least make an arugument that it's a zero sum game: if you're not a deconstructionist Lacanian commie you can't get published or hired at a university, if you don't stage offensive hollow spectacles with naked Wagnerian sopranos swinging from trapezes and electric guitars added to the orchestra you can't have a first-tier music career, or whatever. (Not my opinion, but the argument could be made.)
But with MG, I don't think you can even go that far. It's a very narrow little niche. Where are the decent, honest, trattorie that are being snuffed out by temples of MG? Are they popping up like Starbucks on every corner? Are they taking away Manny's breakfast business?
It seems like a very, very small piece of the pie to generate as much emotional heat as it does in the OP and that's where I tend to agree largely with Dom. and Kenny. I have read a lot about MG and developed no real interest in it. At least no interest that corresponds to the time and $ commitment required to investigate. So I haven't. Whatever they're doing, it has had zero impact on my dining life.
In the end, as other posters have pointed out, as soon as you apply heat to protein, you've done something "unnatural." After that, it's all about your skills and your imagination and your taste as to how well or poorly you utilize the always evolving technology.
IMHO.
