More likely, there were 99 other bugs that they had clearer metrics related to monetization that they prioritized (not that this bug didn't impact monetization - I bet it did, just not in a way they were measuring). Or that their QA engineers identified and flagged as high priority or major new features with their own bugs and regressions or whatever. These things get lost in the shuffle. More likely there were 1000s of bugs in the tracker, probably 10s of thousands.
