Will people care - not convinced - its not as if airline food has ever been more than mediocre.
Will people notice - I believe so, and will see it for what it is, a penny pinching exercise.
I can't say it bothers me much. The other low cost operators have been doing it for years and I'm used to going from morning to evening with just a shop bought sandwich. I remember someone saying on here recently that they needed to take a bottle if water from the lounge to rehydrate on the way to the gate....some things are nice to have but hardly essentials in getting from A to B.
