It’s mostly based on what he feels is good.

One of my main issues is, seeing his code in the past decade... It feels like this guy hasn't coded in a collaborative environment in years.

His personal opinion tends to get on the way with code that's easier to read from a team perspective. And "Uncle Bob" pushing that as the defacto way to code.

This happens from Influencer types who are so detached from the industry for decades and are no longer aligned with problems real engineers hit.

It's not that he's wrong. It's that his perspective is outdated.
