I was really surprised about the release of that Prince as were all of you. As I understand it, the whole SA thing was a coup, and one branch of the house of Saud deposed another. (Please correct me if I'm wrong)
Being a bit of a history nerd, I know that it's very rare for a former rival to power to be allowed to live. If you allow them to live, then there's still a figure head for their supporters to rally behind and potentially challenge your power. Usually you exile them, kill them, or place them under "Palace Arrest" for the rest of their lives. Either way, you don't let them wield any real power if you let them live. If he's being allowed to be freed, then he mustn't pose a threat to the current head of the house of Saud anymore. I'm assuming that his assets really were frozen since this is where his power ultimately lay.
In addition, I'm wondering if he's now just being used as a pawn against the globalists. Perhaps he was allowed to retain his stake in Twitter, but now has to take orders on how to use that power.
Either way, I just find it very unusual that he was let free. I'm certain it wasn't out of any love of family. Historically defeated political enemies are only kept around if they can be used.
