Technically agile has never been about actual programming, it is a process to plan and coordinate programming. Aka a process to 'manage' programming. So I'm not sure why one would be surprised that managers have more interest in it than programmers?

Agile got its first burst of popularity with Extreme Programming, which was all about programming (and how programmers work with business people). TDD and continuous integration both came from XP.

It's only in more recent years that the programming focus has been stripped away.
