Twitter CEO, Elon Musk, has announced that he intends to sue Microsoft, alleging that the company has “unlawfully” trained its artificial intelligence using Twitter data.
On April 19, 2023, Musk responded to a post announcing that Microsoft would be discontinuing its support for Twitter on April 25, which includes Smart Campaigns and Multi-platform, by tweeting “lawsuit time,” indicating that he was considering taking legal action against Microsoft.

Musk accused Microsoft of illegally using Twitter data to train its artificial intelligence system, specifically suggesting that the company may have been extracting user messages to develop its AI-powered services.
They trained illegally using Twitter data. Lawsuit time.

When a Twitter user opined that “charging for API was killing Twitter traffic from the outside,” Musk responded, saying he was “open to ideas.” However, he maintained his stance that Microsoft was “demonetizing” Twitter data by removing ads and selling users’ information to third-party entities.
I’m open to ideas, but ripping off the Twitter database, demonetizing it (removing ads) and then selling our data to others isn’t a winning solution

Wired reported in March that Twitter’s API costs had increased from $0 to $42,000 per month, with some users being charged more than $200,000 per month. Nonetheless, Microsoft did not provide a reason for discontinuing support for the social media platform. It is worth noting that this decision was made after Twitter stopped providing free access to versions 1.1 and 2 of the Twitter API.
On February 2, 2023, Twitter announced that both versions of its API would no longer be free as of February 9, 2023, and instead, a paid basic tier would be introduced. The company emphasized that Twitter’s data sets are among the most powerful in the world, with billions of Tweets sent each week and hundreds of millions of users sending over a trillion Tweets over the years. Twitter also reaffirmed its dedication to making access to this data fast and comprehensive for its users.
Essentially, Microsoft’s decision to discontinue support for Twitter means that its users will no longer be able to produce, manage, view, and schedule Tweets or access their Twitter accounts through Microsoft’s products.
