Without scrum, if a CTO wanted to ask how an individual developer is doing, they could ask their line manager. With scrum, a CTO could just dig in to some of the many dubious reports that scrum generates. They could look at an individuals burn-down on tasks, and compare them across developers/teams. No matter how stupid this sounds, I've seen this exact thing being done by company Directors.

Decisions are made. Developers are moved to different projects, or given shitty bonuses, or constantly hassled to make their scrum metrics look better.

Just because you don't go to a stand up doesn't mean your not micromanaging, or enabling micromanagement as it is usually the line manager using scrum as an excuse to account for every hour in the day. Sometimes that is due to pressure from up high for various metrics to improve, etc. Other times they are just douchebag managers that don't know what they are doing...
