Frameworks are used because they provide a lot of functionality for zero dollars. You then sell the SPA to the client including that functionality for non-zero sum. The part in which the site stutters and the like, comes after the client paid and it's too late. There are also clients that want a website done in Angular. That's what they want and that's what you have to give them. These are two use cases I found for frameworks and these are the reasons they exist.
