It wasn’t particularly cool to be a young person who liked the Dead back then. They certainly are an acquired taste, especially in recordings of their live shows. Not everyone wants to listen to a 15-minute version of “Eyes of the World” and compare it with an 11-minute version of “Eyes of the World” from 17 years earlier. In the 2010s, the Grateful Dead just wasn’t in the air; it wasn’t of our time.
