Twitter accuses Microsoft of unauthorized data usage.

Elon Musk’s personal lawyer has sent a letter on behalf of Twitter to Microsoft CEO Satya Nadella accusing Microsoft of violating Twitter’s developer agreement. The letter claims that Microsoft may have been in violation of “multiple provisions” of Twitter’s developer agreement “for an extended period of time.” Examples of Microsoft violating Twitter’s developer agreement include using the API for “unauthorized uses and purposes” and Microsoft not informing Twitter of “any use case for six of the eight Microsoft Apps that it continued to operate until last month.”
