Honestly, I think your both wrong >:0)
Most people would freely allow Infopop to add their hacks. And Infopop rewrites anything they do happen to add, so the code is original. Compatibility is not an issue, because the code will actually be infopop's addititon.
I believe the main reason is that they do not want to add any more user confusion, or increase the already high server load produced by the UBB... Many of the hacks add tremendous unneed overhead.
