That second bug they describe would have allowed them to mess with inventory in a warehouse. They could have easily "disappeared" millions of dollars of products. Some of these other bugs would have required apple to disclose PII leak disclosure which could do tens of millions of dollars of damage to their company valuation.
You'll find, if you talk to people that do this work professionally, that bugs where you can tell yourself a story about the millions of dollars you could make are not uncommon, and that the rack rate for generating those bugs doesn't scale with their hypothetical value. I've done multiple projects for FIX gateways at exchanges. Those are fun stories to tell yourself! But those projects weren't even especially lucrative.
