I totally understand Waterfall vs Agile. Story points, grooming, estimates, continuous release, potentially shippable product, etc.
I actually agree with the Scrum Guide [0], so my problem isn't with Agile; it's with this specific Agile Consultant who doesn't seem to "get" that process is often a proxy for talent/trust/respect and is just winging-it/BSing us all.
Imagine Bill Lumbergh from Office Space with a ton of two-day CS[a-Z]+ certifications who has never written a single line of code, designed a relational database, spec'ed out an API, etc. micromanaging every meeting while fundamentally misunderstanding the concepts of "collaboration" and "cross-functional teams." He knows what to talk about but has such a superficial understanding that he doesn't know why it's useful or when to apply concepts. Google 'Cargo Cult Agile'
