Why doesn't CNN allow comments? Does your opinion not matter to them?

CNN doesn't want opinion contrary to their own-which they consider as the Correct one. 

CNN is the worst News Media source and is hell bent on bashing Trump. This is obvious from their poor ratings (poorest of all mainstream sources). It became more obvious when their CEO, Jeff Zucker, was exposed on hidden camera pushing bash Trump articles and changing the slant of a story to fulfill this delusion. This is why they don't allow comments. Most people can see the fake news in their stories and thus comments would expose them further.

Their bias and lies are too easily revealed by comments from critical thinkers.

Don't watch it that much. They seem okay to me.

your opinion is of no concern

TROLLS TROLLS AND MORE TROLLS!!! Many media outlets have stopped comments as most are just a bunch of hate!

The problem is that places like the Fox News website become bullhorns for Russian troll farms and contentious angries who spend literally every one of their retired seconds attacking people. There's not one objective poster and you find that even completely neutral stories about cats become dumps for Hillary/Obama angst.

On one hand, I don't go to CNN.com because they don't have the comment sections, but on the other, they don't serve a purpose except to drive clicks by providing outlets for angst. One could say they take the high road, but unless they tell us, we don't know the real reason.
