That’s what I thought which seems like a. Crazy scamYeah that's what you'd do. The reason they do it though is so that way someone can't just go to the lowest tier and then download all of the videos. Rather they'd have to do them one by one for all future videos forcing you to keep the subscription with only the more expensive tiers getting you previous videos.
Thats my thoughts at least.
As an aside isn't that just beaten by doing their more expensive tier every 3 months and going through the backlog every time?
Especially with how many exclusive they have
