X, Elon Musk's social media platform, has been using user data to train Grok, an AI developed by Musk's xAI company.
The company recently added a privacy setting that allows users to opt out of their data being used for AI training, but it's turned on by default.
The Irish Data Protection Commission is investigating X over concerns about the new setting and potential data privacy violations.
X is also facing scrutiny from the European Commission regarding its compliance with the EU's tech regulations, which could lead to significant fines.
