Thats fake and a lie, and they were exposed quickly about that.

Is that occurrence enough to conclude that all their reporting, on everything, is flawed? Because if so I think I could find similar examples from effectively any mainstream source, and any partisan (HuffPo, Breitbart, et.c) ones as well.
Who exactly should we trust when our criteria exclude everyone?
August. CNN edits footage of sister of man shot by Milwaukee police to make it sound like she was calling for peace. She was calling for riots in white cities.
November. Random street interview? Nope, their own cameraman. https://www.youtube.com/watch?v=QSfS2u-SmoI
Repeatedly and continually edits/mistates Trump remarks, not just on Muslims and Mexicans.
Repeatedly libels Assange with false statements about his charges.
"hands up don't shoot" never happened.
The list goes on and on, and your second question is irrelevant.
For instance, in the recent case where Buzzfeed released a massively unsubstantiated intelligence "dossier," CNN reported that Buzzfeed had done it and that it had been given to Trump and Obama in a briefing. Those two pieces of information are important and valid to report. CNN never said the document was accurate and didn't itself publish it specifically because it's not verifiable. How is that "fake news?"
Edit: You also did not answer my second question.
