I'm challenging it as nonspecific, unhelpful name-calling.
What is the difference between "processed" and "cooked" food?
Can you really draw a non-arbitrary line between the two?
Does it just have to be cooked by someone else? Are there techniques which are kosher and are just "cooked" while others make it "processed"? Is it a set of ingredients which make the distinction?
Does baking soda make a food processed? Sodium citrate? Soy lecithin?
Could you go through Modernist Cuisine and classify each recipe as "processed" or not?
