Freemium is almost always a scam, remarkably for games where it degenerates into "pay-to-win". As a parent of two young tablet users, I'll happily pay a decent price for any game they want, but I won't allow them to spend even a single cent in in-game crap.
It's kind of scary the number of games aimed at children that have IAPs of £69, and parents sometimes don't know enough to prevent their children spending hundreds of pounds on IAPs.
I wish we'd crack down on this kind of abuse, but it's an arms race, and at some point hard to distinguish objectively. There's no solution without some parental responsibility... many parents are just too lazy, the hand a device to their kids and hope for the best. Parenting takes some effort; my children's devices have parental control apps (I use and recommend ScreenTime), as for purchases of any kind they have to ask me to put my password every single time because I don't check the "remember" checkbox, it's not terribly hard.
