Poor management is a separate issue from agile. Even so, I would rather stay on a poorly managed agile shop than go back to a waterfall shop.

As far as the "values on the left", I like to explain them as a 55/45 split (and adjustable depending on your reality): we still deal with processes and tools, we just take a second to think whether a process is actually needed when we can just talk to someone instead.

Example: on a small team, you might just ask "can someone please approve my changes?" instead of having a whole jira workflow with code reviews and approvals.
