Here's how I see it: there is all the products and systems and adventure design meta that exists out there, and then there's the game you bring to your own table. If something doesn't suit your table, then you won't bring it to your table. But to denounce its existence in the sphere of crafted products as inherently "the wrong way to do it" is just supremely narrow-minded.
As example: I believe that OSR stuff is largely a masturbatory rehashing of ground already covered, but I also understand that other people enjoy it and want it and pay money for it, so while I can declare that it doesn't suit my table's needs, I can't in good conscience say that it's the "wrong way" to make tabletop games, because that's a wholly subjective conclusion based on my admittedly narrow interface with the industry.
I think some of you may be falling into the same trap - you don't use something, or don't like the way it works, so it's automatically the wrong way to do it. I'd disagree, and point to the audience that actually uses those products as proof.
