I get your point, but this sounds like you didn't read the post you're replying to. At least the way I read their post, snori74 isn't presenting some absolute position of authority, but rather is describing their experience from running the course (and I assume working as a sysadmin) as to what is effective for the students. Putting forward what works best for most students doesn't exclude other ways of consuming the content. A student motivated to consume the content more quickly can easily discover the github themselves, or ask the question on reddit. Your preference for consuming the content all-at-once is a valid one, however it's right for the content creator to set up the course in a way that maximises the outcomes for student - especially when there is an easy fallback to the all-at-once model. I'll also add that having a 'class' of students doing the course with you is something that a lot of people would appreciate, as they can discuss the challenges and successes they see with people experiencing the same things at the same time.
