They decided to have crazy small upgrade timeframes. Instead of 'once every 18 months' on average, they decided to go every 12 months.

Many I know are still running El Capitan and will move to macOS Sierra when High Sierra comes out due to core apps no longer working / lacking updates to the latest macOS offering.
