how can you improve if there is no dialog
The UAE doesn't have a self-advancement culture, it's a capital-backed monarchy that imports pretty much all of its research and production; in other words it piggy-backs on the knowledge produced in other societies. There is no advancement through dialog in the country itself.
They're effectively at war and are freaking out about capital flight which poses a unique existential risk to them especially.
I imagine most countries in that situation would clamp down on freedom of speech and prohibit sharing photos of missile strikes. This would include most of the ones that pay lip service to freedom of speech in peace time.
Ukraine does this too.
