Word documents will be saved to the cloud automatically on Windows going forward

If this report is accurate and the change is made quietly and automatically as it predicts then how does this not end up with the mother of all lawsuits? We have several clients in sensitive industries and contractually it is very clear that we must not upload data for those projects anywhere. Surely many others do as well. Anyone working in industries like healthcare or security could get in a lot of trouble for uploading data even once.

If you are working in Healthcare or security wouldn't Onedrive be disabled and therefore it can't autosave to the cloud?
