At least on ENWorld, I agree, outright derisive statements are rarer, usually it's just a "I don't like 4e because of X", where X is usually not 100% accurate. Now if you went to, say, the Giant in the Playground forums or (shudders) Reddit, it's a whole different kettle of fish.
Its scar tissue. People got so used to receiving so much ridiculous hyperbole and/or inaccurate put downs that when they see something that even smacks of moving in that direction, their reactions are already primed. I've seen enough of it in other contexts over the years to recognize it when I see it.
