Everything Watchtower does is to further its own business interests.
Business is not good if you kill too many of your employees, and meeting three times weekly (plus field service, elder meetings, judicial meetings, preparing for meetings, filling out stupid reports, etc) was contributing to an attrition rate in excess of new employee (converts) recruitment. So Watchtower reduced employee working hours to stave off excessive attrition.
From the employees’ perspective, the general response was something to the effect of “Thank GOD we have another FREE evening per week!”
