I think the issue with Ping not succeeding was more that expecting consumers to connect and interact with Ping, through iTunes, simply based upon musical preferences/interests was just too focused for most people. On Facebook and Twitter, you can follow and connect with music artists, friends, other areas of interest (cars, sports, politics, etc.), and since most people don’t live their lives around listening to music, you get more out of other social media connections, than Ping could offer.
I kind of get the same vibe from AppleTV+. I have had it since it started (got it with my 11 Pro Max purchase) and hardly ever watch any of the shows, even those I should want to watch. It always feels like I have to get out of my normal entertainment loop (Netflix, Prime or RCN) just to look through a handful of show options, so I end up skipping it more than watching.
