I personally believe it's a valid excuse. Amazon should be included in the blame and should play a larger part in helping to provide automatic scanning for sensitive data, virus/malware protection, automatic data protection policies and other tools that can automatically detect/protect information. It's the lack of (local enforcement?) of data protection laws as well, similar to how a bar has to ID patrons before serving alcohol or lose it's license to serve. There simply needs to stop being a Wild West mentality in IT. At a minimum it shows the importance of design & UX.
