Left commentator David Sirota is launching a new webcast ("Podcast" is an Apple-centric term that people still use, long after "pods" became "phones" -- appcast, maybe? no, please).
Unfortunately he's using Patreon to pay for it. That's a new-ish e-commerce platform that several indie content providers, such as James Howard Kunstler and Radio War Nerd, have embraced.
The Patreon model isn't based on subscription -- they call it "fundraising." That is, fundraising in perpetuity.
You can't make a one-time payment for x months of listening, in the manner of say, a magazine subscription. You "pledge" one of several tiers of support and Patreon bleeds this chosen increment out of your credit card or Paypal account each month. You don't have a credit card? Someone call law enforcement.
This puts the onus on you to cancel. If you die or become disabled the charges accrue to infinity. Also you can't buy single webcasts.
Would love to "support" certain authors but not if they're going to use Patreon's "shady porn website" model of commerce (repackaged as a "hip startup" model of commerce). It's rent-seeking, it's Silicon Valley, it's bad.
