I'm not a Facebook user, but it seems to me that "promoted" (or bribed) posts could be very damaging to their business, because it confuses what's interesting with what has been paid for. If the idea takes off then users are increasingly only going to see commercial spam in their streams, and not stuff that they're actually interested in. At some point the noise becomes greater than the signal.
