Personally speaking, bad defaults are never fixed forever. They're fixed once per machine, or once per account, or once per install, or in some cases, once per update. The first encounter is annoying (especially so if it takes a while to discover that the annoyance can be turned off). Later encounters build on the original annoyance, which grows to hatred. Especially for folks working in IT dating back to that era, setting up countless machines, that's a lot of exposure to bad defaults.
