I don't disagree, but micromanagement is a loaded term with a negative connotation to begin with. The fact is, whether a certain manager or tech lead behavior is considered micromanagement is highly dependent on the IC's experience, skillset and their ability to deliver on higher-level goals. There's a continuum between micromanagement, coaching, and abdication. As a manager you want to stay in the coaching zone, but what that means depends on the project and individuals in play.
