The investor threatened to sell his shares if Musk turned down the chance to buy the company.
The founder and angel investor said in the letter that he was bidding for the company at $18.53 per share and that he had secured funding for the deal.
The letter is similar to the one Musk wrote to Taylor when he offered to buy the company.
Musk wrote a letter to Taylor.
Free speech is a societal imperative for a functioning democracy and I believe free speech is a platform for that.
The company will not thrive or serve this societal imperative in its current form despite my investment. The company needs to become a private one.
I am offering to buy 100% of the company for $54.20 per share in cash, a 50% premium over the day before I began investing, and a 38% premium over the day before my investment was publicly announced. I would have to rethink my position as a shareholder if my offer is not accepted.
I will find a way to make it work.
This is what Raisini wrote.
I invested in Twitter because I believed it could be a platform for free speech and I believe free speech is a societal imperative.
Since you acquiredTwitter, you have not kept your promise of free speech and the site has become a breeding ground for online hate and terrorism. The company will not thrive in its current form under the current owner. The company needs to be turned into a public company where members will own it. The governing body of Twitter is formed by these members and under a leadership that respects free speech and doesn't spread misinformation.
The funding has been secured for the purchase of the micro-blogging site.
I am offering to buy the entire company for $18.53 per share in cash, which is 14.26 billion, as I don't think the current valuation is accurate. If my offer is not accepted, I will need to rethink my position as a shareholder and inform my fund that I am withdrawing my investment.
There's a lot of potential in the social networking site. I'm the right person to open it.
The company was bought by Musk in October. According to Musk, his aims for the site are to focus on free speech and to crack down on bot accounts. He said the changes he wanted to make wouldn't work in a public company.
Since Musk took over, he has laid off thousands of workers, faced an exodus of advertisers, and seen a spike in hate speech. His leadership has been criticized by a wide range of people.
"As soon as I find someone foolish enough to take the job, I will step down as CEO of the company," Musk said at the time.
According to his website, Raisini is a music producer and DJ who has been an angel investor at companies such as Apple. According to the company's website, it represents and books celebrities like Afrojack, Steve Aoki, and David Guetta.
She has been critical of Musk. He was called apathological liar, a charlatan and a Super Villain by Raisini.
The letter to Musk was written by a London based company. The British Government's register of companies list the business as inactive.
The company did not respond to the request for comment.
