I dislike them (and many other news sources) because they've transformed from a "this is what happened" model to a "this is what you should think" model.
Worse than that I find they are among the worst offenders when it comes to refusing to provide primary sources for things.
Person X said a bad thing and you should be angry about it because of XYZ, but, failing to actually link to the tweet/video/etc which allows you to see what actually happened, how is that acceptable?
I don't think CNN's reporting (such as it is) has materially changed. It was nearly half opinion-based shows from the day it launched. The only thing it excelled at was live or realtime reporting, since it was the first dedicated 24-hours news cycle. Even back in the 80s it focused on emotion porn (save baby Jessica!) as much as actual news. It's probable that your analysis has changed more than your content has.
I absolutely hate that practice and CNN is far from alone in doing it. It's become extremely common. When it comes to mainstream news CNN tends to avoid outright lies, but they do omit a lot and their bias comes out in what they choose to report on and how they talk about it.
