I agree, but I think it can be formulated in a better way. I.e. it's not about saying "no", it's about having a meaningful conversation about priority to reach a shared understanding with all stakeholders why we are doing the things we are doing. Saying "no" can be a result of this process, but this doesn't have to be the case. Also, saying "no" without proper clarification can give you a reputation of hard to work with, which may result in people going around you, which reduces transparency and increases politics.
