Did you ever tried to work with Lotus SmartSuite? I did, suffered a lot... and had no choice but going to Office to have work done. When we switched from Lotus Notes to Exchange/Outlook, you heard sighs of relief.
I used OS/2 also, and it was a dead end because IBM too didn't believe in it. WordPerfect was so busy to protect its DOS cash cow it missed uers quickly moving to Windows.
Even Borland, one of the few companies that could score against MS on its own field, committed suicide when it decided it needed to buy Ashton-Tate while true RDBMS were already replacing dBase & C.
Sad to say, but most of the competition was actually worse than Microsoft - MS did its best to crush them, but they did their best to release more flaky software than MS did.
More or less the same happened among Adobe, Corel, and Micrografx. Adobe was able to move from Mac to Windows and beat both competitors, that spent time finding new ways to annoy users.
Linux desktop suffers from the same problems - many so-so application you can try to replace Windows ones, but you have to accept a lot of compromises and suffer to get professional job done. Unless you want to make a statement, you'll go the easier route.
Thereby Nadella can keep on piling up mistakes, and for a while the ship will keep on staying afloat. But he started to annoy users a lot with Windows 10, and this can be a mistake with far reaching effects - especially if more and more mistakes will be built upon it.
