I had no idea all the major news sites had an .onion Secure Drop website.
I wonder how many leaked news they receive per year.
However, the vast majority are either:
1. Completely fake, because someone on 4chan/Reddit/an internet forum/social media wanted to see how many journalists they could prank with false information.
2. Uninteresting or pointless to write about, since they don't describe newsworthy stories.
So the amount of actual, legitimate leaked news stories they receive a year is likely a lot less than the amount of stories they receive through these systems in total.
