Because it makes the Conquistadors' conquests of the New World seem more appetising? Because it downplays the indiscriminate conquering of the Americas?
Spain commemorates the day Columbus discovered America as its national day, as it ushered in a golden age for Spain, which is true enough. But with the atrocities inflicted by Spain (along with the other European powers) on the natives in the New World, it may have become harder to feel that such a moment should be celebrated.
And tales that the Aztecs simply handed their lands to the Spanish, rather than the Spanish conquering it, may help people feel a little less weary about the celebration.
But I am merely speculation. Plenty of retelling of history tends to decorate it as best possible (or omit the bad parts) for our side. In much the same fashion, I'd imagine Austrian history classes simply stops in 1866.
