Nintendo console games still cost $50, and seem to outsell $1-$5 games despite the fact that the vast majority of users already own a phone, and consoles cost extra (and there are more than two platforms to choose from.) So I'm going to go out on a limb and suggest that the market does not consider these to be equivalent products.
The still costs $50 is interesting to me, because inflation adjusted this is a pretty steep discount. The 30% stayed the same, but inflation adjusted on something like this the revenue netted is down to what 15% would have previously got you.
All I’m really getting at is that the layers of complication are thick. I feel like one could unwind this with a lot of effort, but I doubt anyone is being utterly fleeced (or is utterly innocent, for that matter).
