Facebook Android app enables silent updates (bypassing the Play Store)

I like how the journalists are going crazy because the update requests a new permission "download files without notification". The articles I read interpret that as "Facebook can update their app and change permissions without telling me!!!!" I wasn't familiar with this permission so I did a quick Google search (something maybe the journalists should have done?) and it is related to the Android download manager added in 4.0 (4.1?).
