JS frameworks seem inevitable. Any time I've worked with native JS in a reasonable size projects, it becomes necessary to create libraries and common conventions, that starts to look like something approaching a small framework. A framework is just common patterns for solving problems. I think what a lot of developers object to is the stack of build tools required to transpile, bundle and link code together when using these frameworks, in addition to the complexity that comes with dependency management, rather than the use of the framework themselves.
