So what happened in the end? Netflix was all set to buy, then Trump complains and Paramount offers an amount, now Netflix no longer wants to buy? Seems like there's some fishy behind the scenes going on although, to be honest, I don't care as much about these corporate drama. The only thing I don't like is the less competition there is, the more expensive these streaming services can be.
No, Netflix and Paramount both wanted it. Netflix did not want the whole company tho (they had no interest in CNN, for example) while Paramount wanted everything. Paramount raised its bid a couple of times, and Netflix stuck at its original number. The slightly surprising thing was Netflix walking away when the WB board still seemed inclined to accept Netflix offer even after the most recent Paramount price raise, but my guess is they were getting cold feet and the latest round gave them an out.
It is unclear what will happen at the federal level with this. The head of the DOJ antitrust division stepped down last month after she complained that there was too much political interference going on (not necessarily about this merger). I have worked with DOJ on several telecom and media mergers, in multiple administrations, and many of the staff I worked with, most especially one in leadership, are still there, so my guess is at least initially it will be given a close look (and indeed, already is receiving that review). A review of this size will probably take until the end of this year, and then there will either be an agreement to let the merger go through after either a divestment or some other conditions, or the DOJ will sue to stop.
State attorneys general, most obviously California with the Hollywood connection, but also others, may sue to stop it themselves if the DOJ does not act. (We saw that in the first Trump administration with Sprint and T-Mobile, for example, although their suit was unsuccessful because the Court found that conditions imposed by the federal government were sufficient to limit the potential harms). So my guess is this will go to the Courts one way or the other, unless Paramount makes a lot of concessions to appease the Feds and the States.
