For some insane reason I am unable to comprehend, the UK government still allows Fujitsu to bid on government software contracts, despite being responsible for all of the false imprisonments, trauma, and tragedy you laid you in your post.

I have a feeling Fujitsu took the blame for mistakes done by the Post Office in order to get future contracts. The contracts are padded to pay fines and damages.
