As I've said before, the facts that you are looking for are not available to the general public. That doesn't mean that a very strong case cannot be made that the Watchtower is not in as strong an economic position as it has been in the past. A person can be convicted of murder in a court of law with circumstantial evidence only. Circumstantial evidence doesn't make it a fact, but it's valuable evidence nonetheless.
I don't assert anything about their financial situation as fact. That would clearly be a misrepresentation. However, the anecdotal and circumstantial evidence all swing in favor of a weakened financial position for the Watchtower. Just exactly how badly they're hurting is another matter. That's harder to determine.
If your point is that people shouldn't speak about these matters as absolute facts, then you make a valid point. But there is no evidence on your side if you're trying to argue that the Watchtower is in a strong financial position. That position could only be based upon pure conjecture on your part
