> much harder than, say, end-to-end encryption over HTTP (which is of course HTTPS), simply due to the fact that the communication over HTTPS is one-to-one Is it? Now, where the people no longer host their own websevers, but leave their content on services owned and operated by other people? HTTPS isn't really E2E here. Can I sign or encrypt some comment before posting it to make sure that only people I granted access to it can decrypt it or people can verify my signature on it with HTTPS?
