Again though, to download a game on 360 don't you need an XBL subscription? And is the 360's online services even still running?
Nope and yes.
For how long the Xbox 360 service remains operational though remains to be seen. Xbox 360 games are having dwindling populations... So Microsoft may not see it financially viable to retain the 360 services over the long term, just like what happened with the Original Xbox.
The 360's servers are definitely dwindling but still active. I mean there are a bunch of notable games with active populations, the X1 has given a boost to those servers as well. Black Ops II is actually listed among the most played games on X1.
The original Xbox is a different story. It had a small userbase, a much smaller number of notable online games, and it was apparently hindering 360 improvements. 360 games are also an incentive to being a Gold user. Obviously there would be more fervor about 360 servers shutting down. For OG Xbox, I feel it was mostly Halo 2 fans that were upset.
