I never understand this type of comment. People don't pay for news so newspapers (which by the way have pay walls) are forced to degrade their service. It seems strange to me. If I have a restaurant and people don't want to pay for my food, making even worse food with worse service doesn't seem a good solution. If I write books and people don't buy them, writing worse books doesn't make my sales better. Why journalists are different? They sell a service for money like all the others, but for some reason they have a special status and it's totally understandable that they respond to bad sales with a worse product. And actually, somehow it's our fault as customers. For some reason we should keep buying newspapers even if we don't think it's worth to save them from themselves.
Using your analogy, if every restaurant in town had a problem where most people wanted to come in and get food for free (and it was an expectation in the industry) and people refused to go in and pay, everyone would be upset they could no longer go out to eat when there were none left. If nobody is interested in paying for their meal, you can't be shocked the ingredient and chef quality drops in turn.
