Eminem practically owns Interscope which owns 2pacs recordings.
Therefore Em pretty much had final say, The Outlawz had SOME SAY (They allowed Crooked Nigga Too, Po Nigga Blues, Loyal To The Game & Hennessey)
Em was responsible for the other garbage (It's not scotch!, its not bourbon! It's just bullshit!)
Em did this to devalue the legend of 2pac, to make himself look superior in the yes of tdays fans. Yes, Eminem is a rap legend, but he doesn't need to fuck up little 12 year olds first listen to pac, they probably think hes a constipated motherfucker who talsk too slow, and does a lot of helium.
