Oh yeah, I didn't mean to imply your current funding had issues. And thanks for hearing me out!
So I think the main draw is there's probably a portion of users who want to donate but:
- Use Linux, and want to donate to 20-30 projects. $5 * 20 = $100/mo, which is a fairly high hurdle, may do nothing due to analysis paralysis.
- Want to donate, but use Calibre irregularly and lightly and are hesitant to donate $5/mo for that (or feel bad about the transaction fee on a smaller donation).
Bre.ad basically allows people to split donations between multiple projects, so they can effectively donate a smaller amount, and splits the transaction fee so the donation goes further.
There's one other feature - Bre.ad has an optional mechanism for distributing a portion of received donations to other projects (like dependencies). This may also be a selling point (so to speak) for some potential donors - that donating to a project supports the entire ecosystem, making them feel like their donations are more effective.
