The problem with media is that the news is now a 'for profit' part of all media.
Journalists are taught to report truth, which is noble and great and lasts until they get their first job in the media. Media companies teach and force employees to editorialize. The "journalists" naturally gravitate towards the media that fits their own politics because advancement is impossible against the current and that's for both the right and left sides of the media.
It was always a for profit thing.
Just the people paying the price has changed.
At one time the price was paid by the many who paid for a fair and as accurate as possible reporting.
Now the price is paid by those who have an agenda to push.
