I don't think it's a problem that they wrote anything "that silly" (okay - maybe that list/hashmap construct was pretty stupid to write originally). Instead, I think it is that they were satisfied with 6 minute load times for years. They should have been profiling this and tracking it themselves prior to launch, getting customer feedback, etc. Someone should have realized this was a problem and then developers on their team should have taken out the profilers and figured out what was up and how to make it come down.
