Lots of trolling with these questions, for sure!
Vomit is right for everyone, not just business. OpenOffice/LibreOffice are feature sparse compared with Microsoft Office. Without getting into minor features, major features are absent or only minimally supported in OpenOffice/LibreOffice. While a full list of missing or poorly implemented features in OpenOffice/LibreOffice would take pages and pages and days to write, here are a bunch that come to mind that I use every day: SmartArt, Ribbon interface, programmable toolbars and menus, support for visual basic add-ins, Visual Basic for Applications (VBA), chart styles, themes, most formatting features for fonts and objects, speed (especially when using Impress, which is a dog), AppleScript support, Automator support, Publishing Layout view in writer or Microsoft Publisher, Notebook layout view in Word or OneNote, Slicers, Spark lines, PowerPivot, sections in Impress, programmable animations, anything to do with Microsoft Access, web queries, Microsoft graph, organization charts, remove background tool, arrange objects, advanced typography. This list barely scratches the surface.
The Microsoft Windows operating system comes with a relatively simple word processor. Large, expensive to make programs like Microsoft Word are not free and have never been included with Microsoft Windows, because the are expensive to make, they're good, and there is a market for them. Word Pad is a light-duty word processor, not as good as OpenOffice or LibreOffice which have a lot more features and are free. But the gap between OpenOffice & LibreOffice and Microsoft Office is a huge one, which explains why people freely pay the price to get the good stuff.
