Elon Musk threatens legal action against Microsoft over Twitter data use.

Elon Musk has threatened to sue Microsoft, accusing the tech giant of using data from Twitter without permission. Musk's comments came after Microsoft announced that it would no longer support Twitter on its corporate advertising platform. Musk did not provide further details or evidence to support his claim, and Microsoft declined to comment. Twitter has recently started charging for the data it collects from users, with a basic plan starting at $100 a month.
