It's not really Excel, is it? But users not reviewing what's happening, not paying attention.
This attitude is at the root of why software is so much worse than it could be. "It's the users' fault" as a real root cause is borderline non-existent, because it can always be obviated in the software, even though the kind of talent that can do that for complex systems is exceedingly rare.
(Actually, many of such products can be made better by replacing them with an Excel sheet, which is a big part of the reason why people who actually need to get shit done end up using Excel.)
