More than that, Trump said yesterday that Netflix's purchase of WB "might be problematic" and that he would be "personally involved in the decision of approving it".
I am not a supporter of most things this admin is doing, but also wouldn't be too sure on this one. I found it interestingly odd that out of nowhere he makes a comment on the deal after attending an event dealing with celebrating music and film. A regular shakedown would have happened before the deal when he met with the Netflix CEO recently, which the added link article mentions and was a person who Trump liked.
And now we see the Paramount thing that leads me to think it fits more with the suggestion that he takes the side of the last person he speaks with, which was probably someone at the same event on the paramount side.
I wouldn't rule out that he now plays them against each other in order to get something from it, but don't think it was the original reason for helping to throw a wrench into it
He's trying to shakedown Netflix to pay fealty.
