There's an entire generation of kids growing up on smartphones and iPads right now, doing all of their schoolwork on school-issued Chromebooks, many without ever touching MS Office.

If they don't happen to get into PC gaming with Windows there are kids aged 5-10 right now that might sit down at a Windows PC for the first time in college or when they start their first job in corporate America. Things could easily follow Blackberry's path very suddenly when new workers are no longer familiar with the tools and there's cheaper, faster, and more productive alternatives that your employees would prefer using and are advocating for.

Yeah but they are doing it on microsoft products related to the web like azure, sql server, etc. microsoft is making money without users ever knowing they are touching microsoft products.

I was there at the time. I can assure you they cared.
