v. Use of Your Content. As part of providing the AI services, Microsoft will process and store your inputs to the service as well as output from the service, for purposes of monitoring for and preventing abusive or harmful uses or outputs of the service.

And while Microsoft has many variations of licensing terms for different jurisdictions and market segments, what they generally promise to opted-out enterprise customers is that they won’t use their inputs to train “public foundation models”. They’re still retaining those inputs, and they reserve the right to use them for training proprietary or specialized models, like safety-filters or summarizers meant to act as part of their broader AI platform, which could leak down the line.

That’s also assuming Microsoft are competent, good-faith actors — which they definitely aren’t.
