Imagine if that was Meta that had over 1B users with their messenger desktop app update functionality that did just that. The loss would be in the hundreds of millions. > But agree that senior gatekeepers should know by heart some places where review needs to be extra careful. Like security pitfalls, exponential fallback of error handling, and yeah, probably this. The lesson here is much better use of automated tests (The app likely has no tests at all) and proper use of basic testing principles like TDD would prevent such junior-level embarrassing bugs creeping up in production paid software. That is the difference between a $100 problem vs a $200M problem. See the case of Knight Capital [0] who lost $460M, due to a horrific deploy.
