I’m well aware of that societal change, but the OP asked about an “active filesharing app that’s still in use today”, and if there are Bittorrent communities with so many seeders that one can get almost any film in a matter of minutes, then that fits the definition.

Using Spotify or Netflix as the example of people getting cold to file sharing is odd. People use Spotify and Netflix because piracy is a service problem, and streaming apps made it a lot less friction is get music and video than running LimeWire.

Notably, Spotify did not exist and Netflix did not stream video until long after the Napster suit.
