This is clearly marketing, and clearly good one. From what I can tell, it's a course that was mostly produced by someone else and will be delivered by someone else, but they recorded Mark Rober - the guy famous on YouTube for glitterbombing people - as the instructor. But their FAQ already states that he will "be able to" look at what students are doing and "may occasionally [..] give feedback", so most likely he won…
I quite like the model of Schoolism.com art classes where you can either pay a monthly subscription for all access, start/finish any time or pay a quite a bit higher fee per course with fixed schedule and personalized feedback from the instructor
