From the above PDF [114 pages of detailed analysis]
that seems to be a very unfair description of what ICL and
Fujitsu [and others] did. "Horizon" was an extremely complex
system [one of the largest and most complex in Europe], which
was processing many billions of transactions, and was not in
itself responsible for the appalling way the sub-postmasters
were treated. I would suggest that anyone wanting to comment
further on the computing aspects of the cases should at least
skim the judgement first -- it's far too long, complicated
and technical to summarise here. FWIW, I started with much
the same attitude as you and Gareth, but then wondered how
well Messrs Gates, Bezos, Zuckerberg, ... might fare if they
were hauled up in court to explain every bug in Windows [etc]
over more than 20 years of use, millions of transactions every
day, millions of random hardware crashes, etc.
