1.The theory states that the "government" is preventing us from seeing the Ice wall. Does this mean that every government on this earth is in on the conspiracy?
Only the governments of the great powers (USA, China, Russia, France, Britain) are part of the conspiracy. The rest of the world, mainly the middle and lower powers, readily accept the claim.
Great powers characteristically possess economic, military, diplomatic, and cultural strength, which may cause other, smaller nations to consider the opinions of great powers before taking actions of their own.
2. Why does this information need to be kept a secret? This kind of ground breaking evidence should be released into the media.
It's kept secret to hide the true shape of the Earth. The Conspiracy is currently doing a pretty good job in covering their lies, as there is still yet a single evidence to expose them.
EDIT: Anyhow, welcome to be part of the society.
