My understanding
Patreon membership tiers:
Premium access (only) content - must be subscribed, and work only for subscriber:
Purchase for your self
(YouTube subscription tier audios may also be played for immediate family only)
If you want to share Sapien Medicine, can do so via a url, eg. YouTube channel, that they become a patron via Patreon, etc.
Some gumroad audios explicitly state they are protected in their description, eg. Black Label
Price and subscription tiers are determined with rationale.
Hope that helps, and anyone please comment if there are errors here
