They actually did a study on it after rolling back to Windows, and it turned out to not have failed due to technical difficulties at all.
If I recall correctly they stated that something like 80-90% of all issues reported during the period were due to badly designed processes - processes which were the same as in Windows, and the number of technical issues actually dropped.

Certainly, the fact that Microsoft promised to build a fancy new HQ in the city if they switched back to Windows can’t have had anything to do with the choice to roll back…
