Emule
eMule was first released in 2002, as an open source alternative client to the official eDonkey2000 client.
Napster would have technically been a 90’s term, since it released mid 1999, but p2p wasn’t really a mainstream thing until the early 2000’s.
But you wouldn’t have been using eMule in the early 2000’s unless you lived through the 90’s so I think it counts.
I also used eMule.
Sorry, I fail to see, how a product that was developed from 2002 until 2017 proves that you lived through the 90’s.
