> 1. Managers Hoard Information. Leaders Overshare.

And, bad managers play politics with information privy to them.

> 2. Managers Weaponize Policy. Leaders Bend Rules for People.

This is absolutely true. There is a saying that comes to my mind, said by a good manager, "Break the rules and justify it, I am here to ratify it"

> 3. Managers “Fire Fast.” Leaders Coach, Then Help People Land Softly.

Also true, bad managers consider people as "resources" to be used and disposed off.

> 5. Managers Reward Compliance. Leaders Reward Dissent.

This is directly related to the control issue. Compliance means control is easy. But this will not prevent them from blame dumping and un-ethical acts.

This “manager” vs “leader” thing is slightly overdone in general.

A manager who doesn’t lead will end up the issues raised in the article.

A leader who can’t manage will face administrative chaos.

I don't think I agree with #5 based on my experiences working in tech a few decades

Dissent is rarely rewarded by leadership to the point I can't think of a single example of it happening
