It probably doesn't help that the prerogative came from Pai's FCC, and of course, they're conservatives, everything they do is EEEEVIL! But honestly, I think they did something right for once. While I don't think kid-targeted shows on commercial over-the-air TV is inherently doomed (especially with the decline of cable), streaming services and the still-intact ad regulations are making the job hard enough that the smaller stations (CW, MyNet, and indies) aren't willing to take the risk (Sinclair tried, but never really knew how to handle it), and obviously if the Big 4 had their way, they could just cram the time full of news and sports (especially ABC with its lucrative college football rights). And besides, it's not like kids were watching the Litton stuff. If you look through the FCC's database, there's data suggesting that most of viewers (about 1 million on average per Big 3 show) are actually older people who didn't bother changing the channel after the news ended.
