LE doesn't work here. As the fine article points out, GitHub Pages does not support TLS on custom domains. With CF, this works.

For the sort of thing that you'd host on GHP, this is totally fine in my opinion. In fact, because CF is a pretty good CDN it likely accelerates page load times considerably for Non-Americans.

(I wish it'd be possible to do something similar for readthedocs, which only has one origin and it's located in North America, but alas this doesn't really work).

Yep, the article is a great example of why one would use CF over LE. I think LE is worth an honorable mention given the topic, but it's not a big deal.
