Well...op left the company, so why should he still get a cut of their current revenues ? That does not seem very fair to the current engineers who a currently able to manage the $200 MM. As far as we know, the company really started working well when they were finally able to replace his crappy code with a better implementation.

The money probably goes to management, who stuck during the entire story - which OP didn't. It also goes to current employees who, by their number alone require more money. And of course to stakeholder who paid for OP $165k when the bank was making $0.
