The Mozilla foundation – who bring you the Firefox browser and other open-source goodies – had a good look at Microsoft’s latest user agreement.

It did not go well.

We had four lawyers, three privacy experts, and two campaigners look at Microsoft’s new Service Agreement, which will go into effect on 30 September, and none of our experts could tell if Microsoft plans on using your personal data – including audio, video, chat, and attachments from 130 products, including Office, Skype, Teams, and Xbox – to train its AI models.

If nine experts in privacy can’t understand what Microsoft does with your data, what chance does the average person have? That’s why we’re asking Microsoft to say if they’re going to use our personal data to train its AI.

They invite folks to put the question to Microsoft here.
