They could remove internet permission from all applications except Google's own Chrome, with that reasoning.
Instead of removing clipboard permissions from all applications, make it a clear option so that the user can give it when needed or only to a specific application, for instance the essential clipboard manager -- that Android incomprehensibly doesn't have and never has, as part of its core. So far only third-party applications have provided this needed feature.
Bundling clipboard with Google's keyboard ( or others like Swiftkey ) that come loaded with unnecessary permissions ( like internet -- I personally never use a keyboard with that permission ! ) and analytics packages is certainly not improving privacy at all.
