ASUS made a deal with someone to send them data for money, so they snuck something in the EULA that said "Yeah, you're gonna give us your data, or you get to have a brick."
Somebody said, "Hey, what if it's a junior high student who can't legally agree to the EULA? That's gonna make it so we could get sued."
Dumb Execs said, "Make it so that you have to say you're 16 first. Kids will just lie and say they are ,so that still protects us from lawsuits."
