It's not about the actual full stack being without servers, it's about the end user not having to deal with anything related to servers. It's just a step further then running instances with any cloud provider. There is still physical machinery in the stack, but you don't have to worry about it anymore. Even if you don't agree with the definition, it is how it is used by most of the people in IT roles currently, so you'd probably have to learn to deal with it.
