It's a start but it's missing worse issues.
While the many companies that harvest more information than they need deserve to have their knuckles rapped, I'd like to see the larger issues with child targeting "adware" fixed more urgently. Many of these apps are essentially a thin wrapper of education over a thicker wrapper of adware disguised as a game. The worst of them are based around was is essentially add click fraud based on unpaid child labor. If that sounds both outrageous and insidious it is. If it sounds outlandish, it is not.
I say one of these games in action on a long road trip once. The driver had handed their pre-K child an iPad during the drive, and opened a game that pretended to be a logic puzzle based on triangles. Superficially it was designed to appeal to parents as a learning/logic app, but on closer observation the game had a "hint" button that would play an ad to get a hint of what the next move in a solution was. I watched in horror as the kid played 40 ads in the span of 30 min spamming that hint button instead of solving the puzzle. It was nothing more than a skinner box built to condition babies to watch monetized ads all day. And the driver was none the wiser as the sound was ducked down during the ads, so all the driver heard was their little genius solving spatial logic puzzles. Evil.
Certainly bust the ad networks profiling and targeting kids and selling their information, just don't leave out the app builders exploiting unpaid child labor to run the back end of their click-fraud botnet.
