The only flaw in the EC is that California and New York get too many electoral votes.
It's not enough to declare displeasure with the Electoral College; by adding the bit about the Founding Fathers agreeing, the author is playing a little psyops with the reader.
Most people who know history know that the states would never have ratified the Constitution if there weren't protections for the smaller states' ability to choose the president.
There is no way that the Founding Fathers would declare the Electoral College to be a failure.
