Sounds like no bug bounty?
It's great if OP is happy with the outcome, but it's so infuriating that companies are allowed to leak everyone's data with zero accountability and rely on the kindness of security researchers to do free work to notify them.
I wish there was a law that assigned a dollar value to different types of PII leaks and fined the organization that amount with some percentage going to the whistleblower. So a security researcher could approach a vendor and say, "Hi! I discovered vulnerabilities in your system that would result in a $500k fine for you. For $400k, I'll disclose it to you privately, or you can turn me down and I'll receive $250k from your fines."
