• Billionaire Tesla CEO Elon Musk offered to buy Twitter again at his original offer of $44 billion.

• Musk plans to make "significant improvements to Twitter" if the deal ends up closing.

• Here are some of the biggest changes Twitter could face under Musk, including looser moderation.

The world's richest man has offered to buy Twitter — again.

On Monday night, after a months-long legal battle, Musk reversed course and sent Twitter a letter saying he would buy the social-media company for his original offer of $44 billion. If the deal closes, Twitter will become a privately held company once again.

So, what exactly does Musk intend to do at Twitter?

We have a pretty good idea of his top priorities based on his initial statement announcing the acquisition earlier this year:

"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," he said. "I also want to make Twitter better than ever by enhancing the product with new features, making the algorithms open source to increase trust, defeating the spam bots, and authenticating all humans."

Musk, a longtime Twitter user with nearly 108 million followers, has been detailing his feelings about the service for years now. Here's what we expect to see in changes at Twitter should the deal be approved by regulators, based on his past tweets and comments.

1. Loosening content moderation

Musk has repeatedly referred to Twitter as "the de factor public town square" of the modern era — the digital equivalent of a public forum.

To that end, he's been critical of Twitter's decision to permanently ban former President Donald Trump from the site, following the insurrection at the US Capitol building on January 6, 2021.

"A lot of people are going to be super unhappy with West Coast high tech as the de facto arbiter of free speech," Musk tweeted in response to the Christian conservative satire publication The Babylon Bee, after it shared a satirical news article on January 11, 2021 titled, "Evil Fascist Dictator Censored and Voted Out of Office."
