You're ballparking 1 million upfront and >250K for a site that made barely 60K a year? That seems extremely optimistic and emblematic of dot.bomb numbers.
You need to look at it as the total value this will provide Stripe. It's a community of people who will buy their service. It's good will too.
Community outreach is a good thing (tm) but I see now way any sane/experienced business person would pay a million dollars for this.
