That said, my point still stands. Additionally, the comparison they did is massively unfair. I'm pretty sure Kaggle competitions have most of the feature they claim it doesn't have (ex: multiple phases, custom metrics, evaluation in environments).
Kaggle has two parts - more popular "featured" competitions which have most of those features, but cost money to host. And then also self-hosted competitions which indeed lack all those features and are more relevant for this comparison IMO.
