I can't say I blame him but he gets it, this is the reality of the click-focused, social media driven 24 hour news cycle we all live in today. We all see it ourselves, not just in sport - there's a clear distinction now between reporting the news and what is newsworthy and creating a media narrative that can be used to fill hours of programming. So Kyrie made some comments critical of the media in a part of a wide ranging interview because of some speculation of what he was saying to KD in a casual side conversation (we even had people trying in vain to read lips and such).
As a result of his outburst the narrative is now "Kyrie is mad at the media" and that narrative will be4 used as fuel for ESPN, Fox and NBC Sports talk shows. Because it can then be split into so many more sub-narratives: Why is Kyrie mad at the media? Do the media deserve his vitriol? Is he mad at the media because they're digging a bit too close into his true desires, which is to team up with KD? Which then can be used to re-fuel the "Kyrie is leaving Boston to join KD at the Knicks" narrative. Etc etc. If you're a producer for one of those shows you're salivating at everything Kyrie just said.
You've got days of programming out of that, and days of people talking about it on social media like we are, at least till everyone gets bored of the topic and they have to find a new (or re-hashed) narrative (which can be "Kyrie doesn't like the young guys").
But this is the reality of any public figure. You agree to do an interview, you lose control of the narrative. The narrative can then be shaped by whoever you did the interview with, and then it will be re-shaped countless more times once it hits Twitter, Reddit and social forums such as this. Gotta take the good with the bad. People like LeBum figure out how to make the media do their work for them. Kyrie's not quite there yet.
