They are in a tricky position when it comes to requesting donations. They have frequently distinguished themselves from other Christian churches by pointing out that they do not require donations and are not pushy about it. Many KHs used to have the "no collections taken" text at the bottom of the meeting schedules that were posted outside.
They have had some videos over the past few years where they have put an emphasis on the need for the rank and file to be more generous, and that already gets them close to a line that it seemed they would never cross. If they are making suggestions around the practice of tithing, I have to wonder how long before they just come out and beg for money or even demand it. I think it would be a disaster, but if they are desperate enough that might be their only option.
It's too late to go back and encourage the membership to earn a decent living, after years of advising them to scrape by and build treasures in heaven.
