Grandma’s sewing store would be hosted on a VPS or Squarespace, and will have a checkbox to provision “secure site encryption” for her without any further work required on her part. (They may charge her money for the certificate, if they’re a scummy VPS.)

This ship has sailed, though: “plaintext HTTP” is available only with HTTP/0 and HTTP/1. This article is discussing HTTP/3, which carries forward the requirement of wire encryption that HTTP/2 argued over for a long time and then incorporated into the standard.

(Incidentally, my grandmother was a Smalltalk and 6502 assembly programmer of educational software in the 80s. She let me read her technical books at age 5. Probably best to find another example, such as “non-technical site owners”.)
