It should be noted, for the avoidance of doubt, that both Saudi Arabia and the Muslim Brotherhood are Sunni. The conflict comes from the fact that the Muslim Brotherhood is Islamist whereas the current Saudi crown prince is pursuing a policy of westernisation and liberalisation (and probably eventually secularisation).
The rivalry is power politics, not particularly ideological. Saudi Arabian state has been opposed to MB for long before MBS and is mainly concerned about a rival political operator.
