Yep! Many liberals in KSA were actually jailed for being against theocracy.. others. were jailed for supporting the arab spring as well... not to mention that many Salafi clerics who were jailed for being against the country as well!
For example; Salafi clerics want sharia law to be a 100% applied or some of them are calling for Jihad in Iraq = those are the ones who been jailed..
Anyone who's against theocracy or supporting the revolution in the western region well be jailed..
But good thing that the Saudi media is run by Liberals.. The daughter of king is a liberal as well.. So, the king made some good reforms that upset Islamists..
