I don't know if that's great advice, but its certainly advice that will help get you promotions and salary bumps.
Like anything there's a grey zone here. Understanding the political realities of a business is highly beneficial and will help you move forward with the company and let you know when to pick your battles. But I've watched people who do nothing but this lose the trust of those at their level. And that trust is crucial for agile development. I also personally feel like pushing back on the company when appropriate can indeed provide a lot of value to the organization. "Why are we doing this meeting?" "We need another week for testing" "I'd like to see the roadmap you are planning". Just don't push back all the time.
