It's a team fault, meant that maybe the PO didnt spec correctly, then the developer implemented something wrong, then this was missed in the code review, then missed in team testing, then missed in testing before going live. Missed in the PO sign off before live...
If anything I would hope that stuff like this by Google helps to encourage orgs to build better processes. If you succeed as a team, you fail as a team. No scapegoats!
