Another twist in this theory might be that the borg starts moving more and more toward a more traditional type religion. For example, they may receive new light that says we must be more appealing to the masses and so you can stop wearing ties to the meetings and in service. Then they may say that you can just wear regular clothes to the meetings. Then they may say that birthdays are ok now etc... This way they can start passing the collection plate. Also this would allow them to keep the money flowing in via religion. This would happen very slowly but it would keep people interested.
Some examples of this are the lowering of the pioneer hours a few years back and now we have the shortening of the meetings. What's next sunday school?
