I think that the point is this: You could literally use a telnet client to talk to all of those servers and it was considered a good thing, maybe even an essential feature. So protocol design was somehow influenced by the need to be fully plain text ASCII streams (and maybe that other options weren't adequately explored due to this restriction)

      Or requires HTTPS, for that matter. (But then you can s_client into it :)

        Admittedly, it’s been decades since I tried this and I was deliberate about saying http and not https.
