Many commenters are also furious about alleged "lowering the bar". Remember than once we take away certain factors from grading, if we do it right, new factors will take their place - it's not just going to be all participation prizes. The idea is that the bar will be higher, but it will be positioned in a place where all students have to jump the same height to clear it.
The general idea is clear, but as for how that could be implemented, I don't know. I was hoping to find out in the article, but I was left terribly disappointed. The way it is written does make it sound like coaching baloney, which I think doesn't do the people trying to improve their education system any justice, it just makes it easy for them to be labeled social justice warriors.
