> A bit surprised the tutorials are all up and available for free...

That was on a presenter-by-presenter basis. Some of the tutorial presenters were just sharing the info and don't mind it going out. We usually get several presenters who do training courses for a living where it wouldn't make sense to give away their next training materials, and I believe some opted out of the recording.

The presentations are a relatively small part of the "PyCon experience". This is seriously awesome.
