There is certainly scope for a more intelligent and nuanced discussion to be had here than what reads like a junior engineer's half baked rant on the uselessness of engineering managers.
Yes there are awful engineering managers just as there are great ones who are force multipliers for their teams. I've known great engineering managers who were great engineers who naturally became an interface for their teams and some who weren't very technical but were great people managers that got great outcomes for individuals and teams.
Org design, culture, complexity, needs determine the necessity of an engineering management function. Do orgs and engineering management functions become dysfunctional? Yes. Can this be resolved by just eliminating the management layer? Hardly.
