I was just playing on the Xbox one and there was nobody anywhere, no other players in the tower, none on Venus, none on Earth, and if there were none in the crucible that might explain why my crucible matches never loaded or gained players. I played for a couple hours, decided to start a new character, and this didn't change. So either everyone abandoned the Xbox one destiny (which seems unlikely) or somehow I've gotten kicked into a server that no one else is on. I keep checking over the next couple of days to see if this changes, but if it doesn't it smacks of a serious problem.
