She doesnt' get 100% of that, she doesn't even get close. Several podcasts I listen to are killing their $2/$3 tiers as it doesn't make them any money. That's also assuming they continue the payment for the full year all 10k of them.
Am I missing something here? The cut that Patreon gets is 5-12% of revenue and processing payments for 2-3$ are 5% + 10c. At worst, she's getting $2.2 for every $3/m user.
Are they rolling in it, no not at all. I'm not sure what your point is, they don't think they can work, it's been going on for a bit, they get a nice community pay out ... do people live on less, yes definitely. But she didnt' win the lottery here.
