“If you were unfairly treated by your employer due to posting or liking something on this platform, we will fund your legal bill,” Musk said in a post on X, adding there would be no limits to funding the bills.

“And we won’t just sue, it will be extremely loud and we will go after the boards of directors of the companies too,” Musk said later in response to a post about nothing changing behaviour in the United States faster than a threat of legal action.

The announcement comes after Musk renamed Twitter as X and unveiled a new logo, marking a focus on building an “everything app”.

Late last month, Musk said monthly users of X reached a “new high” and shared a graph that showed the latest count as more than 540 million.

The figures came as the company was going through organisational changes and looking to boost declining advertising revenue.

X executives have claimed strong traction in usage after Meta Platforms launched a direct competing platform called Threads on July 5.

After 17 years with an iconic blue bird logo that came to symbolise the broadcasting of ideas to the world, billionaire Musk renamed Twitter as X and unveiled a new logo in July, marking a focus on building an “everything app”.

Musk earlier in July had said that the platform’s cash flow remains negative because of an almost 50 per cent drop in advertising revenue and a heavy debt load.

An upturn in advertising revenue that had been expected in June failed to materialise.

Since taking over Twitter in October, Musk has said he envisions an app that offers a variety of services such as peer-to-peer payments – an idea that mirrors the widely popular WeChat app in China.
