30+ years ago, I believe, Microsoft had a saying 'Embrace-Extend-Extinguish'. Back then there were many other software brands such as:
Word Perfect my wife assures me much more user-friendly than Word
Quatro Pro spookily similar to Excel
Supercalc- much much better than Excel in those days!
Etc. etc.
My theory is that MS EEE'd them all. Their operating system wouldn't accept other software apps. This way all software competition to Microsoft was Extinguished.
I have never considered MS to be innovative; new versions of their software merely generate fresh and more revenue for them by causing confusion like the latest version of Outlook. I have just endured a stressful morning thanks to MS Teams; I'd far prefer Skype!
I'm afraid that all the stupid problems we now encounter with MS software started 30+years ago when all the competition was eradicated.
Put it this way: If I owned 100% of the worlds production of bread, I could sell stale loafs and get away with it, make a fortune- charge top dollar for 2nd rate bread. Be a Billionaire!
Same thing with MS in my humble opinion.
I could go on and on....................... but I won't
