> Is there really any secret today that would be problematic if made public 30 years in the future?

Sure. For one, that all the major earthquakes in the last 30 years, resulting tsunamis, destruction and loss of life, were manmade and intentionally caused by, say, Nabisco. Also, it would be a little shocking to the public if it were revealed there are no humans left, only alien-hybrids.

Both of these facts would be quite irrelevant when ultimately discovered. It is hard to make people care about anything that happened 30 years ago that did not affect them personally, and in the latter case the alien-hybrids would have to just... accept the fact.
