Ensuring that private (intimate, sexual, etc.) photos and video chats
actually remain private, including from the government (see e.g. GCHQ
collection of Yahoo! users' video chats).
Protecting against misbehavior by ISPs and other services (e.g. privacy
violations, censorship, etc.).
Protecting against mass surveillance programs and other forms of state-
Protecting against abuses of power by police forces e.g. surveillance
of peaceful protesters (this is unfortunately relevant not only in
places like Hong Kong, but also in Europe and the USA).
These are examples of legal and ethical reasons why people would use
end-to-end encryption or whole disk encryption, which is what the
current debate is about.
