Why I said that the Governing Body only changes things because it benefits them, can be seen in nearly every big change they've made.
For example, why were District conventions reduced in length from 7 to 3 days long? Because attendance was dropping off, and it cost them money to rent these facilities. Why was the Watchtower and Awake magazines shrunk until our letterbox junk mail, are thicker? Because the Organization realized that householders were just throwing them in the bin and they were wasting money. Why do Kingdom Halls have no building insurance? Because the Governing Body, knew that they could save the premiums by getting its free labor force to repair its damaged properties for nothing.
Its just the same pattern now repeating but in organization context. So you can bet the Governing Body hasn't dropped the reporting requirement for nothing ... particularly since its been such a great tool to pressure conformity.
The reasons will manifest themselves in due time, however we may have to wait until next years AGM to see if these changes are part of a trend.
