Musk's purchase of the social media platform was agreed for $44billion at $54.20 per share.
“Free speech is the bedrock of a functioning democracy, and Twitter is the digital town square where matters vital to the future of humanity are debated”, Musk said in a statement.
Jack Dorsey has now given his seal of approval to this takeover in a series of tweets.
On top of this, Dorsey also praised Elon Musk's aim of creating a platform that is “maximally trusted and broadly inclusive”. He said that this is the "right path" for Twitter.
“I’m so happy Twitter will continue to serve the public conversation”, he said. “Around the world, and into the stars!”.
The deal with Musk and Twitter was agreed, despite the site initially introducing an anti-takeover measure. However, they agreed to negotiate with Musk as he updated his proposal, assuring the company that he had secured the financial backing.
