Why is almost everything written full of deception?

I read a lot of News Stories, Scientific Papers and Stories here on Medium.

Almost nothing is fair and balanced. Almost everything is written to make a point or change the readers mind. Everything is a sales pitch.

I have written thousands of responses to stories here on Medium trying to point out these deceptions. Trying to present some balance the stories missed. I am often taking a devils advocate position, not defending what I might believe but sometimes pointing out the flaws in stories that support positions that I too support.

The ends do not justify the means. The full truth will set us free. Even a tiny distortion or deception damages our credibility.
