Democracy and a free society tends to go with the ability for media to report both good and bad things. Because we know the press can and do report the bad things, we have a higher level of trust when they report the good. If people know that bad stuff will eventually make it to the public domain, they are incentivised against being corrupt and tend to be honest, and do things to the best of their ability.
Without transparency and openness in the information we read, we end up in a despotic society (e.g. Soviet Union) where nobody trusts anything they read and nobody is willing to spend money or invest anything.
On a similiar theme, Boeing are embarassed about the 737 Max, but the freedom of media to report has ensured that our Govt leaders are doing (eventually) what most people perceive to be the right thing
