One possibility is that the PO bosses thought that there had always been a high level of theft and that Horizons system was finally uncovering it. The ultimate case of projecting your own failings onto others by grasping and immoral execs?
I mean seriously, if you were a criminal, would you go to all the trouble to run a post office for years?

From the testimony, it seems that is rather likely. PO managers seem to have had a pretty bad attitude to subpostmasters in general. I think the general view was that subpostmasters are essentially village shopkeepers, drawn from a population that would happily engage in grift if the opportunity presented itself, and therefore needed close monitoring.
If you went to all the trouble of running a post office for years - would you mind ‘losing’ a package or two every once
in awhile to pad your retirement?
