>Tons of small and big business runs on Excel, and there's simply no alternative in the market for it, with 100% compatibility. And considering the ammount of stuff running on obscure excel formulas, and excel macros, it will take a lot of time before one arrives.

I was thinking about this compatibility problem the other day. Usually someone moving between office suites (MSFT Office, Google Drive, LibreOffice) complains stuff broke, then they give up / drop it / work around it. I was imagining an ideal path would be to document these cases of incompatibility as bugs/issues in LibreOffice. Describe the difference and how it should work, then LibreOffice fixes their software to better match. I don't know if this already happens. Personally I avoid all office software like the plague and try to work with plain text files and vim. I just hear about these issues enough that I'm mildly invested in the situation by now.

I tried to tell a friend about WYGIWYM stuff like LaTeX, groff, and Typst the other day. He seemed more interested in "figuring out" why stuff broke when changing between office software. I tried to tell him that MSFT doesn't follow their own spec and everyone else has to reverse engineer it, resulting in implementation differences. Plus MSFT's own implementation being proprietary so it can't be easily copied. I'm not sure the weight of the situation got across to him.
