I think this comes from a supportive mindset, but working with homeless populations over the years I think they often were more at risk than many other groups. Significant numbers deal with domestic violence or otherwise abusive relationships, as one example, where these kinds of security issues can be life or death, and they often lack the digital hygiene skills many folks take for granted (I think half the folks in a computer lap I worked with left their password saved when chrome offered to remember it, or even wrote it down in a text file).
