Microsoft Drops Twitter From Its Ad Platform. Elon Musk Threatens To Sue

Microsoft Corp. said its social media planning and scheduling tools for advertisers will no longer support Twitter.

Musk responded to the announcement by accusing Microsoft of using Twitter data “illegally” and threatening a lawsuit. The billionaire, who bought Twitter last year, is changing the company’s policy to charge businesses for access to its stream of data.

The software maker is the biggest investor in OpenAI, the AI research lab Musk co-founded before falling out with the team and leaving in 2018. Musk is now establishing his own rival AI effort.
