It just seems like your opinion but even in that case I don't see why we are talking about intention? Ultimately the world would be better if one just said truth so there's no excuse for this
Principles are not the same as intention though. Even if some articles are biased and have certain intentions, I don't mind if they are principled and stick to truth.
I expect principles from both. I don't expect non biased reporting however. I guess you are conflating them.
Principles in this case is to own mistakes, correct them and value truth and yes I do expect boosters to own mistakes. Your first two examples don't show lack of principles - they just show bias and intentions.
