That doesn't stop your likes resulting in targetted advertising to your contacts (depending on their how-closely-they-follow-you settings, presumably).

For instance I sometimes see "sponsored links" of the form "<sister-in-law's-name> likes <retail-outlet>, here is an offer that they have on at the moment" - I've never liked <retail-outlet> on facebook let along done that and subscribed to see absolutely all posts from them.

Yeah you're probably right about that. I think they can each individually hide those though, right? In any case, I agree that the UI for this is terrible and that's probably by design to make it less likely that the masses will hide everything.
