> If you're interested in truth and not principles, why do you bring up principles?

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.
