Agree with all the comments on laziness/tawdriness. But the base laps it up, so we shouldn't expect anything else at this point.
But for all the sound and fury and attacks on the press, what's striking about the list is how thin it is. Ross's mistake was huge, with major legal implications, and he deserved the suspension he got and arguably more. CNN in #3 was a meaningful error but boiled down to the wrong date on an email that was definitely sent, and was quickly changed. The Scaramucci story was also bad but he was a private citizen and 3 people were fired for it. The rest (not counting the opinion stuff or the sweeping "I am not a crook" #11) are mostly just fluff - misphrasings, posts or images about minor issues that were initially inaccurate or misleading. Almost everything, major and minor, was corrected or retracted within 24 hours of publication. At least 2-3 were single Tweets that were retracted within an hour. The WaPo one was literally a reporter retweeting a mislabeled picture from his personal account then fixing it 30 minutes later and apologizing.
A corrupt or malicious media wouldn't require searching this hard across dozens of outlets and hundreds of journalists/reporters/writers for 10 things they got wrong over ~15 months and padding it with things like feeding fish or a brief mixup on whether a bust was moved inside a room or out of it. And they wouldn't be retracting stories or holding people accountable for them. Look to how Fox handled their phony Seth Rich story for an example of what that kind of approach looks like. Or umpteen Gateway Pundit fabrications if you're a more online type.
There's a separate conversation about slanted presentation or characterization, which stories are promoted/deemphasized, etc, but when talking about false information this just paints a picture of media orgs that make mistakes. Relatively few major mistakes, but one is too many, so the offenders need to work on the process that led to those mistakes. I'm having a hard time picturing when that wouldn't have been the case.
Of course, it's all moot because the President's endless griping has little to nothing to do with actually wanting more accurate reporting. But still.
