Several vaccines are most effective when administered to infants. I'm not explaining to infants the benefits of herd immunity, I'm doing what's good for them as their parent.
Are infants property? That seems to be the level of reasoning on display here.
There is clearly a continuum between infants and adult roommates, but as the person who pays the internet bill, I decide what the default DNS server is. Those old enough to be bothered by that are welcome to choose a non-default DNS server.
To argue that this is somehow immoral because children shouldn't have their default DNS provider dictated to them is asinine, an argument most likely to resonate with teenagers without kids of their own.
