I worked in Saudi back in 1980 and spend 18 months in “liberal” Dubai and other Emirates in 2104/15. Scratch the glossy surface and it it is apparent to me that virtually nothing has changed in the psyche of the Arab Middle East.
I could be wrong, of course, but history and contempory evidence tells me this power grab is no different that previous incarnations. This is the House of Salman forcibly deposing the House of Saud, and none of them gives a tinkers cuss about anyone who is not of their family.
