Politics is accruing and deploying political capital within an organisation - or less abstractly, building relationships and using them.

What you’re describing is a particular form of manipulative and divisive politics which is performed by insecure, desperate or selfish people.

Many engineers are not good at building relationships (the job of coding isn’t optimal for it after all), so painting the people who are good at is as narcissistic may be comforting but isn’t correct.
