"All those rushing in the criticise, how confident are you in you processes?"
Confident enough to know it works through testing.
I could defend an honest mistake, not a short sighted lazy one. It could be argued that they were not lazy (who knows, maybe their testing matched their design), but they were clearly short sighted. Either they were or they were not designing to be bullet proof, which was it?
All they had to do was test for the worst. This isn't a after school special, not everybody is winners, not everybody deserves a rewad. At least they owned it. They could of said "You're holding it wrong."
