It is not just micromanagement, it is also the rest of the business culture. Ego-less development and placing the team over the individual can great for productivity. These productivity gains accrue to the profit of the wider company and _might_ partially flow back to the team, possibly as a bonus or possibly as promotions. However, effacing yourself for the team is unlikely to result in the kind of visibility needed for career progression and with software salaries being what they are that can mean a difference of hundreds of thousands in income over the years. In a way, scrum and its team-based mechanics form a kind of prisoners dilemma where the first team member to claim credit will gain much more of the value generated than their peers. These incentives need to be taken into account in any framework based on teams cooperating, because they have the potential to rapidly poison any team where people are jockeying for promotion.
