In esoterica the cross represents union of the male and female, opposite polarities, the same as yin and yang. The stauros is male and the crossbeam is female. Intersection of the two is the key to enlightenment. The same symbolism is in the Star of David, with the intersection of two triangles. Everything the Watchtower does is to intensify what's wrong with religion: Do everything possible to remove the female aspect of God from everything. That's probably the main hidden reason they hate the cross. Their God is angry, male, and narcissist, just like most men today. Or at least that's what they tell the dubs. If you look into Kabbalah, "Jehovah" comes from the Hebrew Iod-Havah, with the Iod being male and the havah female. If you look into Fritz Springmeier's book "Be Wise As Serpents", there is a chapter called "The Cult of the Double-Sexed God Jehovah", you'll see that the WT leadership certainly knew that Jehovah was both male and female. It may seem too subtle to be true, but once you understand a little about metaphysics and the power of thought and emotion, you'll see that this is how religion has shaped human consciousness.
