The article was written based on older memes about those corporations. I agree with the sentiment of it, but it's unfortunately stale info. The article is a year old, the merger was a year before that, and the graphics are sourced enough to probably track down.

From the article itself: "Of note, this infographic is dated and does not reflect the current media owners of some of the news outlets."

This is a writer who found something controversial and refreshed the topic, but added a disclaimer that it's based on older pieces of information.

All that said, I'd be wondering if it's a placement piece for YouTube's NowThisWorld user/channel. Or if it's young editors at the website just stirring things up for traffic and/or relevant content for their audience.
