Great idea for a plugin few questions..

what is the licensing of this? is it gpl, etc?
I looked for licensing info, but couldn't even find the file to download, even after finding the tab for install instructions, which say "Download the latest version of the plugin on this page".

If this is not copy-prohibitive, is it documented well for changing the call back params to use a different third party connection instead of patreon?

As much as I would LOVE to use this, it truly sounds close to perfect, I have strong concerns that locking in this kind of content blocking would put us in a pickle should patreon decide to cut off access to us and our members - seeing as they are changing their terms to be more censoring, there is no way I could count on this and be locked in without being able to change it over to hatereon or some other service for payment, and proof of previous payments.

Perhaps you guys can open up an API to connect with s2member, or press permit core, or other paywall and content drip systems from wpmudev and others... Systems that are already handling this kind of content blocking for non-paying members / supporters..

Those systems have already dealt with numerous issues, have support, and work with a multitude of payment processors should one or more become a problem, it's trivial to switch and not have a dysfunctional site because of that.
