While advocating privacy-enhanced technologies or the privacy-preserved attitude is good, the tendency is the opposite. The underlying reason for the status quo lies in law/governance, economics, and technology. Merely focusing on the last aspect, technically, digital privacy is managing and maintaining the copies of bytes because this is what happens when a data exchange takes place. As a result, a new copy is created. For the record, I presumed a data exchange is part of the process as, in your case, it became the input for an M.L. When the data owner agreed to share the data, she issued a consent underpinning the agreement of the data usage. The technicalities up until now are solved, more or less. Maintaining and managing all of it from the user's perspective is comparable to cookie consent on every single WEB page nowadays. Hence, these users no longer even read the terms and are blindly looking for the accept button. Therefore, digital privacy (or rather confidentiality), merely considering technical aspects, is quite far from being a solved problem. When we also discuss economics, it becomes even more challenging.
