I feel like this article is trying to make this seem like this is becoming a widespread thing despite the entire thing being about hockey. In my experience hockey was always the sport that the wealthier households participated in due to the costs (equipment, rink time, travel, etc..).

As a parent with two younger kids I haven't run into this at all so I wonder how much of it is more sport dependent where the company controls the infrastructure. Maybe I'm being naive here but I struggle to imagine this is going to make its way very far into other sports where you simply are out in a field.
