You can thank IRL privacy activists for the lack of cameras in every room in each house; Just imagine how much faster domestic disputes could be resolved!

Sure, there’s a cost-benefit to it. We think that privacy is more important than rapid resolution of domestic disputes and we think that privacy is more important than stopping child porn. That’s fine as a statement.

Rubbish. The reason Facebook doesn't want to demand ID for most users is that it adds friction to using their product, which means fewer users and less profit.

Sounds like Facebook and I have the same interest, then.

Unsurprising lack of response to this statement. It's 100% true, and any cost-benefit calculation of privacy should account for it.
