world's richest person wants to buy Twitter

“Twitter has a purpose and relevance that impacts the entire world,” its CEO, Parag Agrawal, tweeted.

"I am deeply proud of our teams and inspired by the work, which has never been more important."

Musk describes himself as a "free speech absolutist," though he hasn't clarified exactly what he means by that.

In a recent TED interview, the billionaire said he'd like to see Twitter err on the side of allowing speech rather than moderating it.

He added that he is "very reluctant" to delete tweets and is often careful when it comes to permanent bans

He also acknowledged that Twitter will have to comply with national laws that dictate speech in markets around the world.
