If you read the Wikipedia article, it points out what MOND advocates say about the Bullet Cluster: they try to handwave it away. It's likely that Verlinde's theory needs a similar solution. Unfortunately for handwaving, over time, the number of weird dark-matter-related observations is growing.
I remember reading about this as an undergraduate and thinking how attractive his ideas were -- I think Verlinde's ideas have been around for some time. Back then it seemed like few people were giving these ideas thought.
I hope more people decide to explore this avenue. It really is a fascinating take on gravity.
His idea deserves some study but a title will "Kills off dark matter" is very infuriating
