Maybe a stupid question, but is this sort of data still shared (with Facebook) if you’re not a Facebook user...?

  Yes. They send names, e-mails, phone numbers and sometimes more information regardless of whether you have an account or not.

  Facebook, LimkedIn et al maintain profiles of people who don’t have accounts. If you subsequently make an account, as soon as they can connect the two you’ll start seeing stuff in your feed based on what they already know about you. Though that’s not the reason they do it, it’s for advertising.

  I think it's a very good question, and yes as far as we know, it's still shared. Information brokers aggregate whatever they find, and this includes data from other brokers as well. With Facebook in particular there's a concept called a "shadow profile", which are supposed to be people who haven't registered at Facebook, but some data is still associated to them.
