2.  The people who have a vested economic interest in other figures are going to spend a great deal of time disrupting threads - as opposed to helping the poor people that actually use their figure of choice.

So, this would explain your increased "participation" in the G3 threads over at DAZ3D forums? Also with Rpublishing releasing a Genesis 3 outfit yesterday (along with a texture set from a vendor), I can't see them risking money on a building a figure from scratch. Figures are not easy things to create, especially if you want to be morphable and flexible. Rendo is a brokerage that sells content and software; if someone wants to sell a figure through them, they don't have a problem with that. But to set aside resources for a new figure? I think they're making a much better business decision to support the current popular figures than risking the business on something new and untested.
