One of their biggest mistakes, financially speaking, was leaning heavily on GFM and treating their Patreon as an afterthought. GFM is aimed at funding specific, one-off needs: build this school in Africa, pay for funeral costs, help pay for my dog's surgery, etc. People have to log in each time and consider whether they want to give their credit card information to this particular request. Great for attention-grabbing and unique events, but terrible for ongoing contributions.
And that's exactly what Patreon is for: set it and forget it. If they'd pushed the Patreon heavily after
Earl, they could have easily gotten up to $15-20k of contributions... monthly. Probably more! Unlike their current "re-engage people each time" strategy, Patreon would be effectively stable, reliable income on a monthly basis. All they'd need to do is lock some exclusive content behind the paywall, and that could be as simple as "Here's a photo of the latest cute baby

if you want to see the full gallery, become a contributor on our Patreon!" Or maybe Kevin gets put to "work" by writing a monthly brief on "why trans supporters are the best people in the world and why transitioning is great." You know, the sort of bullshit they post on Twitter for free, but could make Patreon supporters feel like they're in a Super Sekrit Good Guy Trans Supporter Club if it's supposedly done just for them as a thank-you. They'd eat that up.
People rarely review their Patreon support, especially if it's small dollar stuff. Even after all their failures, they'd still have a really solid chunk of however many people got lured in with the Earl bait. If you're donating $50 monthly to good causes to feel like a good person, why mentally engage with the $2 of that that you decided to throw at the trans ranch?
Fortunately, Phil's a terrible business manager and zeroed in on the one-off platform.
