Bit of a nitpick, but the comparison with the reversing of the MS Office formats is a bit tenuous, and somewhat revisionist.
Competitors and open-source applications were reverse-engineering the Office file formats long before Apple iWork was a thing, and arguably no-one really gets it right because in order to get it perfect you’d have to reproduce the Office application layouting engine exactly, bug-for-bug. Even Microsoft doesn’t get it 100% from release to release.
