Mate if the world was literally about to end in like a year what the fuck do you expect the government to do about it?
"Oh boo hoo, the authorities decided that they should hide our imediate and inevitable destruction to stop society from totally colapsing as long as possible! How dare they stop mobs from pointlessly rioting and murdering innocents by withholding information that would lead to such an outcome!"
Your alarmist claims just make you look stupid. At the very least you could resist the urge to shrink the window past the point of no return when you lie to get people riled up for your cause.
