Lots seem to forget that TfW (I think it was ATW at the time) didn't have the hindsight when these were ordered that they would be 2 years late otherwise it would probably be a different decision. Anyway they are at TfW short term and that is probably not going to change. At least they are now getting delivered.Without wanting to go over old ground (all 769 threads are full of "why is this still happening?") TfW needed rolling stock to allow 150s to go for PRM work and to bridge the gap between the Jan 2020 accessibility deadline and new stock arriving. 153s were seen as uneconomical to convert due to the loss of seats when adding an accessible loo whilst keeping Pacers was seen as politically untenable. Portabrook were offering cheap 'new' DMUs obviously at a reasonable price and within the deadline - were TfW naive to go for them? Perhaps but given the alternative was probably more expensive in loco hauled services then I don't blame them.
