Congress has screwed up
They did it better in 1998 when they extended copyright by 20 years. This meant that 20 years later they were showered with yet more mouse gold. This time, extending by 50 years, means that they will not get any more bribes ^w research contributions for a looong time.
They should, at least, make the mouse pay!
PS: 20 years in 1998, actually a bit more complicated, but still.
