I mean, this guy probably does deserve to be fired... But Callimachi deserves to be fired right along with him, and she isn't. They were terrible at their jobs.
The reason here highlights two problems: First, that he might be being made the scapegoat, probably to distract from the huge failure of the organization as a whole that that podcast was. And second, that the twitter cancel culture mobs seemingly only want targets they find acceptable; they deliberately didn't target Callimachi but happily settled on him.
It highlights how hypocritical and toxic the cancel culture mentality is. And I don't think it will change if they keep on succeeding.
