Twitter accuses Microsoft of improperly using its data

Twitter on Thursday sent a letter to Satya Nadella, Microsoft’s CEO, accusing the tech giant of improperly using the social media company’s data.

In the letter, which was reviewed by The New York Times, Twitter said Microsoft had violated an agreement over its data and had declined to pay for that usage. In some cases, the letter said, Microsoft had used more Twitter data than it was supposed to. Microsoft also shared the Twitter data with government agencies without permission, the letter said.

“Microsoft may have been in violation of multiple provisions of the agreement for an extended period of time,” Alex Spiro, the personal lawyer for Elon Musk, who owns Twitter, wrote in the letter to Nadella.
