I find it appalling how people believe there is such a thing as unopinionated journalism. There's not, especially in a world where much media outlet income and even access to information comes from its association with state actors.
In some - if not most - parts of the world, there are even supposedly impartial media outlets whose most income comes from advertisings for state campaigns and politicians' agendas.
Exclusive perks and access to state authorities for journalists is also another problem. While many people might say that it's essential for them to have close access to presidents, governors, and lawmakers to inform the general public, no one can argue that this doesn't have implications in behavior.
You get reporters traveling alongside politicians in taxpayer-paid aircraft, bypassing immigration protocols, getting celebrities associated with authority, and their integrity is likely going to mold even if it is hard to see.
