Is it like possible that they thought it through to take advantage of individuals with conditions like ADHD?
It's meant for kids so parents would be the ones paying. Obviously they're trying to profit and it does seem a bit overpriced (though there are extra logistical costs for anything to be medically approved, so it's not comparable to a normal game). But I highly doubt there was any intent to take advantage of people here.
Yeah, merits of subscriptions in general aside, targeting subscriptions specifically to people with ADHD is a next level of underhanded business.
