I'm struggling to understand how the numbers make sense. The One Army patreon alone shows 1600 paid members, with the minimum paid tier being $7/month. With ~10% fee for Patreon, this should come out to: 1600 * 7 * 0.9 = $10080/month.

That alone should sunstain them according to the numbers they are giving out themselves. Do the other non-Precious-Placstic parts of their Patreon make up such a big share that not a lot of that goes to Precious Plastics?

I'm less skeptical about Precious Plastic than a lot of people here from an idea standpoint (I think even if it doesn't make a huge impact ecologically, I think its a nice project for educational purposes). However I've become quite weary over the years of projects that don't have a good financial track record asking for many AND are not being transparent enough about their financials to allow potential backers to make sound judgments. If they present as a non-profit (no matter if they are registered as one or not), they should also aim to fulfill best practices about being a non-profit.

Still low...
