In fairness, the number of spreadsheet documents MS Excel has spontaneously irrecoverably corrupted on me vs. the number LibreOffice has are far from equal.
If I had something critically important I needed to do and couldn't afford to lose or go wrong, I would still trust Excel over LibreOffice without even a moment of hesitation.
This from a FOSS and Linux desktop user of many years.
Maybe if we spent more attention to productivity apps, not changing GNOME UI...
