Some societies need a good turning upside down.

Egypt is one of them. There is value in most of the value being in the shock value. Egypt has already done the sorts of things you suggest. It doesn't work. Putting up porn actually makes a lot of sense from a decision matrix perspective here. First of all despite the pretense otherwise Egyptians watch a lot of porn (like most countries). It's sort of a great "in your face" mirror to a country rife with hypocrisy.

It's not like the authorities give much breathing room for more nuanced protest anyway. They're already in for a very unwelcome visit to the slammer if they are caught. Might as well go as transgressive as possible while you still can.
