The term only became popular after Trump's win [1], not while it was happening, which is forever (I once read in a real paper newspaper about an amputee who had donkey's legs attached in place of his own). This suggests people don't like it because they went looking for something to blame for his winning. It's entirely a partisan political concern, not a fundamental one.
