No you gave retarded, false answers. They're not making money off of 2pac being on stage, they were already getting paid, and they were not trying to gain any new fans.
When people are doing shows and they do songs that they made in the past with artists who are now dead, is that taking advantage of them? That's a rhetorical question by the way. When people say RIP Mac Dre, is that taking advantage of him? Again, no need to answer that.
This is just comical how people are making a big deal out of this, it really is. It was something cool that they did and almost everybody enjoyed it. Some people just need something to whine about.
