From Wikipedia:
Since the mid-2010s, [Matt] Taibbi's reporting has increasingly focused on culture war topics and cancel culture. He has also criticized mainstream media and their coverage of Donald Trump and Russian interference in the 2016 United States elections. His writing has since polarized readers and fellow journalists. Ross Barkan wrote, "Taibbi's critics view him as a reporter turned red-pilled culture warrior chasing subscriptions — or worse, a middle-aged male no longer at the vanguard, aggrieved that younger journalists are now leading the fight for justice." Barkan continued, "The liberal-left especially loathes the way Taibbi equates the right- and left-wing media." On the other hand, "Taibbi's defenders say he hasn't changed. Rather, it’s the world that has grown more illiberal and hysterical." However, Barkan concluded that many critics of Taibbi were more concerned with Taibbi's priorities and "how one of the most talented reporters of his generation should wield his formidable powers in this uncertain age." Taibbi rejected criticisms that he has changed, arguing that Donald Trump "fundamentally changed the business".
