Multibillionaire Elon Musk, in a meeting with Twitter employees, has hinted at possible job cuts if his offer to buy the company of 44 billion dollars is realized.
He also addressed topics such as remote working, freedom of speech and possible extraterrestrial life, the BBC reported on Friday.
Musk spoke to staff for the first time since launching his bid for the firm in April.
He has said he could pull out of the deal if he is not given false account information.
In a wide-ranging video call with Twitter employees Thursday, Musk said layoffs at Twitter would depend on the company's financial situation.

"The company should be healthy. Right now costs exceed revenues. However, anyone who is a significant contributor should have nothing to worry about," he told employees.
He also stated his preference to work from the office, except on occasion.
Musk, who is the boss of electric vehicle maker Tesla and rocket company SpaceX, also discussed the possibility of life beyond Earth, although he said he had not seen "actual evidence for aliens".
Meanwhile, a group of employees at SpaceX — where Musk is chief executive — called Musk a "frequent source of distraction and embarrassment" in an internal letter to company executives Thursday.

He was also sued for $258 billion later in the day by an investor in the cryptocurrency Dogecoin, who accused him of running a pyramid scheme to drive up its price.
The complaint filed in New York alleges that Musk "used his pedestal as the world's richest man to operate and manipulate the Dogecoin pyramid scheme for profit, exposure and entertainment."
