Elon Musk has threatened to sue Microsoft for allegedly using Twitter data without permission.
The billionaire’s warning, via a tweet, came after the tech giant revealed it would drop his social media site from its corporate advertising platform.
Microsoft’s service uses AI to help ad buyers manage their social media accounts in one place.
Musk said the firm had trained it “illegally using Twitter data”, adding: “Lawsuit time.”
Microsoft has indicated that its service will still support Meta’s Facebook and Instagram.
The company declined to comment when contacted by Sky News.
Twitter no longer has a press office, instead responding to journalists’ enquiries with a poop emoji.
Microsoft’s move comes after Twitter started charging companies for the data it collects from its users, which is essential for targeted advertising.
For a minimum of $100 a month, Musk’s platform says it helps businesses “understand, track, and benchmark the conversations and perceptions surrounding your brand”.
The service is known as an API (or application programming interface), and Twitter previously provided free access.
