I mean, I sort of get what they are saying and I hate the overuse of Instagram filters probably much more than the next guy, but the odd relevance people place towards getting an image "directly out of the camera" is bizarre considering the incredible number of decisions (sometimes correctly, often not) the average digital camera has made for you in getting the measured light into a jpeg.
Personally I much prefer to shoot in RAW and then post-process because cameras, as amazing as they are in some ways, are still incredibly dumb when it comes to context and intent and I'm going to do a better job at getting the white balance, dynamic range, contrast, etc right (for how the shot was intended) than the camera is.
