Beacuse anyone with a budget had Excel already - and had to use Excel to be able to use other peoples' spreadsheets. LibreOffice is not bug compatible with Excel.

Look what Excel had tro do to replace Lotus 1-2-3. Including making 1900 a leap year beacuse Lotus had the error.

I love free software as much as anyone, but when I'm forced to use a spreadsheet I'm glad we get office at work. The UI/UX of LibreOffice could use a lot of improvements

Because the world runs Excel, not LibreOffice Calc.

For someone working outside IT but who has coding skills, it's great. My previous work computers have been tightly controlled by IT and installing libreoffice on them wouldn't have been permitted.
