This may be a hot take, but I have a problem with the way that first article equates "extremely overpriced" with "scam".
A scam is when you've been deceived or defrauded.
If you consent to pay $10 a week for an app that doesn't provide what it claims to, that's one thing, and that should be actionable. But if it does what it claims to, not liking the price does not equate to being a scam.
I misunderstood your criticism; so while I do believe such subscriptions are scams in the sense that they prey on victims via deception and the presence of such actors undermines trust in the marketplace thus undermining fluid trade, thus such scams should be prevented - that's really kind of neither here nor their, because that's at best a laudable goal, not some kind of requirement for Apple as app-store manager.
