How about political dissidents and political prisoners? The data that they are able to retain are of prime interest to historians 50-100 years after the events, and are oftentimes the only way for us to get any insight into the era. It's feasible to imagine that their hard drives outlive them, it's much harder to imagine that those hard drives are readable 50 years later when somebody can get to them without being prosecuted. Imagine if the 1930s of the Soviet Union happened in the digital era, and you'll see what I'm trying to say.
