that means that even if the scrum lord is a complete fool, the staffing choices made by your boss are horrible, your team is the worst, and you hate node.js but have to use it, just do your tickets and keep moving. do not suggest big "improvements" or things to "think about" as they will flag you as a class of person that is a potential rival or insubordinate, which may bode horribly for you. keep engaged but lightly so: no heroism.
and trust me, if you're asking this question, you have shown you are not prepared to go toe to toe with "them" on their turf, so don't even try. you will get annihilated. as an engineer you probably aren't sensitive to how power dynamics manifest in day to day interactions - that's why you /must/ lay low and see what's up, despite any drive to do otherwise.
