They are in 95% of situations. Most managers and product people are just insecure about the fact that they know next to nothing technically about the products they manage, and instead of getting out of the way of the people who do, they feel the need to constantly insert themselves in the process, directly lowering project efficiency, to justify their roles existing at all. “Managing (internal) relationships” provides no value to the company’s clients whatsoever, it only exists to reinforce a company’s culture or prop up someone whose job is probably not that important in the grand scheme of things.

A client buying your product couldn’t give two fucks whether your manager asked you an ice breaker that ate 10 minutes of a 30 minutes meeting. And managers that don’t understand this are self interested parasites, or just completely inept. Most of the management I’ve worked with have been a combination of the two.
