This is the wrong way of thinking. Angular allows you to be flexible by not strongly enforcing a convention, a convention that may not fit your needs technically. If you find Angular terrible, then it doesn't fit your needs. Move on and find another framework. Nobody is telling you to stay. However, writing "unmaintainable code" is the choice of a developer and his team. That has nothing to do with the framework.
