Microsoft has been threatened with a lawsuit from Tesla and Twitter CEO Elon Musk, who claimed the Big Tech firm “illegally” trained its artificial intelligence on Twitter data.

On April 19, Musk tweeted that it was “lawsuit time” in response to a post reporting that Microsoft would cease supporting Twitter on April 25 across its online social advertising tools, Smart Campaigns and Multi-platform.

The Twitter boss alleged Microsoft “trained illegally using Twitter data,” implying the firm mined user tweets to help train its AI-powered applications.

Microsoft didn’t explain why it was winding down Twitter support although Twitter’s API fees skyrocketed from $0 to $42,000 a month and in some cases are priced upwards of $200,000 per month, according to a March report from Wired.

Musk made further allegations that Microsoft is “demonetizing” Twitter data by removing advertisements and “then selling our data to others.”

Microsoft’s decision to ditch Twitter means its customers will lose access to their Twitter accounts through its tools in addition to being able to create, manage, view and schedule Tweets.

Microsoft’s decision comes a few months after Twitter stopped providing free access to the Twitter API for versions 1.1 and 2.

Academics have been hit hard by the huge price swing. Over 17,500 academic papers have been based on Twitter data since 2020. Now they’ve been largely priced out.

Cointelegraph contacted Microsoft, which declined to comment on Musk’s claims and its decision to scrap Twitter ads support.

The software company is now reportedly developing its own AI chips to power ChatGPT to deal with the rising development costs for in-house and OpenAI projects.

With a $2.15 trillion valuation, Microsoft is behind only Apple as the second-largest company in the world by market cap, according to Google Finance.
