With news that Facebook shows all your friends’ data to companies
when you interact with their Facebook apps, many people are interested
in figuring out how to turn that setting off in their Facebook
dashboards.

EFF’s Gennie Gebhart has written up a howto explaining, step-by-step,
how to undo this setting that a) shouldn’t exist and b) shouldn’t be on
by default and c) should be one click to turn off.
