Microsoft gets most of its money from big corporate customers. Some of those customers are obligated by law to not leak sensitive personal data to servers in USA soil, because those customers have the missfortune of being in countries with strong privacy laws, functioning civil societies and sometimes even left-winged governments. I know for a fact that the product in question, "OneDrive", it's sometimes mandated in those companies as a backup solution for the company's computers. All it takes is a whistle-blowing incident or a chat with a journalist for this to become a major blow-up for Microsoft, with companies forced by tribunals to back off from contracts with Microsoft.
