The negative reactions to the new SNAP restrictions are because much of it make no sense. In the states that have implemented there has been mass confusion at many stores as people can't figure out what is eligible and what is not.
For example at one store there was confusion as to why a ready to eat cup of cut fruit packaged with a plastic spoon from the store's deli department was ineligible, but a slice of cake packaged with a plastic fork from the store's bakery was eligible. Apparently the cake being made with flour makes it OK, regardless of how much sugar is in the cake and the icing.
