Doctrinal shift.
For those who do not see this as a doctrinal shift, please note what the Watchtower taught with regard to Proverbs 19:17 up till this point. As late as last year, this verse, in WT dogma, meant something entirely different.

4. To what does Jehovah liken our kindly giving to others?
4 Jehovah considers acts of loyal love expressed toward his servants as being rendered to him ... Proverbs 19:17. Is this scripture implying that Jehovah takes note of every act of kindness performed in behalf of lowly ones? Can we conclude that the Creator of the universe considers himself to be indebted to mere humans who perform deeds of mercy ...
5. What questions will we now consider?
5 Jehovah invited the prophet Isaiah to speak on His behalf, revealing His pleasure in having faithful humans take part in the outworking of His purpose ...Today, thousands are demonstrating that same “Here I am! Send me!” spirit in taking up challenging assignments in Jehovah’s service. Still, one might ask: ‘Does my individual effort really matter? While it is gracious of Jehovah to allow me to volunteer and participate, will he not provide whatever is needed to fulfill his Word no matter how much I personally choose to do in his service?’
