Holograms of deceased musicians

The usage of holograms performing to crowds has increased in recent years and it seems like it is set to continue for the foreseeable future. Just two months ago, a hologram of Roy Orbisson toured the UK and performed "Oh, Pretty Woman" to crowds across the country. The photo above is actually of a hologram of 2Pac, who performed in front of an audience back in 2012. What is your opinion of it? 

I personally don't agree with the idea of holograms being created for deceased musicians. Their legacies are being exploited and all it does is take away who they were as people. I would hate to see a hologram of John Lennon or Kurt Cobain, for instance, selling out tours and performing all over the world.
