Totally fair reaction! Here's our honest thinking behind it.

We deliberately avoided credits/usage-based pricing because as founders using this in our own creative workflow, we hate the cognitive load that comes with it.

If I don't like a voiceover/variation, I should have the freedom to regenerate it until I'm happy without thinking about whether it's "worth" a credit.

That said, we could be wrong! Genuinely curious what you think would feel fair?
