The UI is actually 80% of the workload of a software project
This may be true for some software projects, but I can’t see how that could be generalized to any project (even any desktop or user facing project).
Specifically for LibreOffice, the amount of work that went into that project is staggering. It’s been worked on for decades, through three different organisations (StarOffice, Sun/Oracle OpenOffice, now LibreOffice), and according to https://www.openhub.net/p/libreoffice/estimated_cost it took thousands of man-years of effort (models are lies, but I’ll believe it as an order-of-magnitude estimate). Surely not 80% of that went to the UI work.
