Yes, they can. It's weird that you think that people can't demand that any aspect of any business change (or end) because they don't like it. That's basically an argument against law and democracy.

Your example is about someone entering a contract, accepting the fruits of that contract, then refusing to hold up their end of that contract. Completely unrelated.
