This is often repeated by developers and it reeks of hypocrisy. Of course management must be implicated, but so must be the developers. Innocent developers are not simply helpless cogs in the machine coerced by management.
This blameless attitude held by many developers permeates the software industry. Whether it's the Volkswagen emissions scandal, ad-tech, or widespread online tracking - these were conceived, built and implemented by developers. And yet developers think they stand apart blameless from the consequences of their shoddy practices.
I wonder if the Fujitsi developers, far removed from the Post Office staff, have ever stopped to consider that the software they wrote ruined the lives of so many people.
