It does make sense, and thanks for posting it.
But, cynically, I have heard IT folk offering similar explanations since the 1970s. The people to blame are the IT people/company who did your job before you and have now escaped with the proceeds of their nefarious activities. Still, that is better than another line that was popular "All the technical systems worked perfectly but the customer wasn't satisfied simply because they didn't like/couldn't understand the front end". And that, in turn, was better than the once ubiquitous GIGO - garbage in, garbage out that placed the entire responsibility for failure upon the shoulders of the user who were too stupid to use the technology. This carefully avoided the uncomfortable facts that the mainframe cooling system was liable to failure, any lightening strike on your building would disable the entire system and that the fault that was plaguing you was an unfortunately designed-in defect created by a sandal wearing, long haired and bearded, mathematics genius, high on speed and other narcotics, at 2.00am in the morning, under immense time pressure because he had been partying for the previous month instead of doing his job.
At one time I used to attend Systems Analysis business seminars that had a familiar refrain - "Some very good reasons why our super mega-system, costing x zillion pounds, didn't work - and why it wasn't my fault".
