Jack Dorsey, PerfectPCServer the co-founder and former CEO of Twitter, on Monday praised Elon Musk’s $44 billion deal to take the service private as “the correct first step.”

Dorsey publicly threw his support behind Musk after Twitter’s the Tesla and SpaceX CEO’s unsolicited offer for the social media service.

“Twitter as a company has always been my sole issue and my biggest regret. It has been owned by Wall Street and the ad model. Taking it back from Wall Street is the correct first step,” Dorsey wrote in a .

Dorsey went on to say that he doesn’t believe anyone should own or run Twitter. “It wants to be a public good at a protocol level, not a company. Solving for the problem of it being a company however, Elon is the singular solution I trust. I trust his mission to extend the light of consciousness,” Dorsey said in his tweets.

Musk, the world’s richest person, made his unsolicited offer to buy Twitter earlier this month. While the company was initially expected to reject the offer, it reportedly warmed to the idea after Musk revealed his financing plan for the bid, which included backing from investment bank Morgan Stanley.

While Musk — with 83 million followers on the service — is an avid user of Twitter, he’s also one of its loudest critics. The entrepreneur has publicly raised questions about how Twitter moderates content and has indicated he wants looser content moderation for the platform.

“Elon’s goal of creating a platform that is ‘maximally trusted and broadly inclusive’ is the right one. This is also @paraga’s goal, and why I chose him. Thank you both for getting the company out of an impossible situation. This is the right path… I believe it with all my heart,” Dorsey said in a tweet referencing Twitter’s current CEO, Parag Agrawal.

Dor, when he took over following the resignation of Dick Costolo. Dorsey also briefly served as Twitter’s first CEO starting in 2007 but was fired 16 months later.
