I think the giant leak is diminished donations since literature became free, an economic crisis, plus financial mismanagement by uneducated, inexperienced, Jehovah-will-bless-us top managers (gb).
That lead to a huge cash flow and liquidity issue. They're not poor, but most of their money is/was tied up in real estate.
So over the last decade they have tried to fix the cash flow issue by reducing costs. They tried to solve the liquidity issue by selling off real estate, but you can only eat up your assets until they are gone. I think more important is thay less real estate means less cost, and that helps their cash flow issue.
What they are doing now is trying to make their financial situation sustainable. Cost are to match the income, which apparently it didn't (for a long time even?)
They're not poor, but bleeding. They're stopping the bleeding now to prevent themselves from becoming poor.
