Bringing attention to the issues of privacy around location sharing is a good cause, so props to the ACLU for that. As it is, Facebook users are complaining themselves that turning off Places entirely involves jumping through several hoops. Facebook absolutely could have made Places more opt-in, for instance, by making people find the app themselves and decide to install it on their profiles. But as usual, the company is more concerned with reducing friction that will stop products from spreading and people from sharing. That’s always going to be problematic for many people. In my opinion, friends checking friends in to inaccurate locations will happen rarely unless your friends are jerks or teenagers. Both of those are (hopefully) temporary situations.
