Now, Elon Musk-owned X allows third-party companies to AI-train on posts published on the platform.
Previously, X had trained its own AI service Grok using the posts, and according to the new user terms that come into effect today, external services can also be offered access to users' content.
However, users should have the option to choose not to share.
At the same time, a new wave of users has chosen to leave X after the American presidential election, which several media outlets have reported on.
X, which previously was called Twitter, has lost value since Elon Musk took over the company two years ago, and selling user data can be a way to earn money, according to tech site Techcrunch. Previously, among others, Reddit and large media houses have chosen to offer their content to AI companies like Open AI.
