The multi-billionaire was responding to the tech giant’s plan to drop Twitter from its advertising platform.
Twitter boss Elon Musk has threatened to sue Microsoft as he accused the technology giant of using data from his social media company without permission.
«They trained illegally using Twitter data. Lawsuit time,» the multi-billionaire said in a tweet.
Mr Musk was responding to Microsoft’s plan to remove Twitter from its corporate advertising platform.
He did not provide further details or evidence to support the claim.
Microsoft declined to comment when approached by the BBC on Thursday.
Earlier, the company said in a notice that its advertising platform would «no longer support Twitter» from Tuesday 25 April.
As a result, ad buyers would not be able to access their Twitter accounts through Microsoft’s social management tool.
