Elon Musk blasted accusations that Twitter is suppressing Substack, the subscription-based website that hosts his reporting, as “false” — after “Twitter Files” journalist and Substack writer Matt Taibbi announced he was abandoning the social media platform.
“Substack links were never blocked” on Twitter, Musk tweeted Saturday.
“Turns out Matt is/was an employee of Substack,” the billionaire then charged.
On Friday, Twitter began blocking “likes” and comments on tweets referring to Substack stories and slapped an “unsafe” label on Substack links.
In response, Taibbi announced he was begrudgingly leaving the platform, saying the changes made it “unusable” for him.
By Saturday afternoon, the “unsafe” labels appeared to have been lifted.
Substack co-founder Chris Best hit back at Musk’s claims that Taibbi — who was one of a handful of reporters Musk granted access to Twitter’s internal communications last year — worked for the website.



“None of this is true,” Best retorted in a post on Substack’s Notes platform, a Twitter rival whose imminent launch appears to have sparked Musk’s ire. “It’s one thing to mess with Substack, but quite another to treat writers this way.”
Taibbi, meanwhile, told The Post Saturday that it is all a “business dispute.”
“All I can say is that I appear to be in the middle of a business dispute,” he said.
