Not to take away from the feat and initiative of doing so without access to source code.
There are a lot of excuses for why this wasn’t fixed but no great reasons.
Bugs happen. Serious bugs happen. They will always happen. Shaming people for bugs undermines institutional robustness against bugs because it incentivizes people to hide mistakes. Furthermore, companies with blame-n-shame culture typically fault users when those users make inevitable "mistakes" statistically guaranteed by bad UX design.
In contrast, transparency is good, acknowledgment is good. Rockstar acknowledged fault and rewarded the reporter, which is difficult. That's a positive institutional arc I'd like to encourage, at Rockstar and in the wider industry.
If you stop at "embarrassing", I'm with you. But when you proceed to "shameful", that's quite different and we part ways.
Not fixing a serious, visible, known bug for six years is what’s shameful. There is nothing positive about neglect like that. It’s kind of admirable that they actually rewarded the guy but it shouldn’t have even got to that point.
Totally agree you should not shame for bugs. The shame is for ignoring this bug until one of your customers finally had enough and fixed it by patching the binary. If it was my company I would feel ashamed.
Managerial problems that allow high-impact, low-fix-time, high-prevalence bugs to exist for 7 years are shameful and are in fact poison to an organization themselves.
Don't mistake the shaming for really being about the bug itself here. The problem isn't the bug, it's the organizational culture that allowed such a massive, easily fixed, widely encountered bug to persist for 7 years in a game that has made them $6 billion dollars over the last few years.
