The recent decision by crowdfunding platform Patreon to remove popular YouTuber Carl Benjamin, aka Sargon of Akkad, may have been a free-speech tipping point for the clinical psychologist. Mr. Peterson and fellow pundit Dave Rubin of YouTube "The Rubin Report" announced plans to build a "better alternative" for intellectuals and content creators.

"We've been engaged in lengthy series of email exchanges with all of the people in our network, and no one is happy at all with what's been happening," Mr. Peterson said a joint video released Sunday. "We've been determining what our options are. We looked at Subscribe Star, but it looks like PayPal decided to cut funding out from them."

At issue is Patreon's decision to kill the account of Mr. Benjamin in early December after its staff was made aware of a guest appearance on a small YouTube channel 10 months ago.
