FWIW, shitty agile consultants have had plenty of pushback too, with comedy sites like https://www.halfarsedagilemanifesto.org/ being set up to point out their buffoonery. I do suggest laughing in their faces when they pull out tripe like that. Sometimes their excuse is, 'well, we don't work for a startup, we're a regulated business' -- well, it's still tripe, there are plenty of regulated businesses with lightweight agile processes.
My favourite piece of writing on this, in fact, comes from the US Defense Innovation Board, and is called "Detecting Agile BS"[1]. Their recommendations may not 100% work for your organization, and that's okay -- tailor it with an eye to outcomes for your team.

I get the sense the authors of agile used words like “scrum” because they imagine software development like a full contact sport; where everyone is fully engaged with all their senses to truly be aware of what’s happening, what’s needed and what is the most important thing to work on. The cargo culting agile consultant approach always feels like an attempt to make software into a repeatable assembly line, and make software engineers into factory workers.
