I doubt he's specifically looking for Angular jobs or likely any job at all. It's likely he's getting contacted by recruiters or just seeing job ads. The current trend is react but I run across node+angular postings regularly.
How many job descriptions do you see looking for "experience in JavaScript with at least one current framework"?
Compare that to the number of job ads looking for "experience with Angular".
I agree that it shouldn't be that way, but the hiring process is badly broken in most places.
You'd be better off in the long run looking for jobs that require Javascript knowledge and are familiar with at least one current framework. Those are the types of companies who will be more likely to upgrade their stack as technology progresses.
