That’s exactly right. Presumably there are still physics majors, who could be repurposed to EE in a pinch. The dominance of CS over EE probably reflects the software (versus hardware) focus of the tech sector right now:

Yup, physics/math types are pretty much already EE's to some degree...

I was a physics major (also CS, but I digress)

It has amazed me how often that knowledge becomes useful when programming real-world applications.
