Maybe it depends on expectations...
My better half and I were both disappointed when we were offered these dry packets of stuff in lieu of what we thought would be a cheese plate-type snack on a 2.5 hour dinnertime so-called "Snack" flight. We were in paid F for a special occasion and found the packets to be a real letdown. In fact my easygoing husband surprised me by saying he would never eat that stuff again.
If it had been a one hour flight or a flight that hadn't formerly had at least a small portion of real food on it we might have reacted differently. Or maybe if it had been a free upgrade and we hadn't intentionally paid more for a better experience. As it was, it seemed like AS had abandoned food in favor of some cheap odd snacks that some food manufacturers were happy to sell for a low price in order to perhaps develop a customer base. Maybe that's not what happened, but your mind can go that direction when you are disappointed.
