Hi Maria,
While it's unfortunate that you were confused by the page and may be upset by it, please be careful about making false accusations.
The page is labelled clearly as for Patrons, and we've already explained why it's set up the way it is in the comment chain above. We can only work with the tools provided by itch.io on itch.io; we can't simply import our own. The Patreon implementation feature is only a few days old and will likely be improved upon, but in the meantime, we can only work with what we're provided.
It's wonderful that you're so passionate about games and good sales practices, but we appreciate the support from our Patrons, and so providing them with the most convenient ways to access their rewards is our top priority, even if it causes confusion to some.
