Eehhh, this does seem dubious as hell. Sorry but I don't have enough blind faith in Mojang to say this doesn't look like money grubbing, cause it damn well does. I really can't see the whole "parents wanting a safe environment" thing being that big either, to warrant THIS anyway. Most parents (That aren't tech savvy) have no idea what their kids are doing on the PC as it is and won't care about this, those that do could usually figure out how to rent another server, or setup a local one.
And, a lot of people seem to be treating these "kids" like god damn toddlers. Most, if not all of them are teenagers, 10+, perhaps I put to much faith in my younger brother (13), but I'm pretty sure he could figure out how to run a damn server himself, it really isn't difficult if you can read.
