Doubt it. A guy rode his motorcycle into the pit on 2010 which started a small "riot" from the crowd. The fest was shut down but they had it the next couple years just with a slightly larger security presence. As it says in the announcement, I think this is strictly a money thing. The fest has gone down in popularity over the years.
Gotcha. from the comments of that article though i just gathered that SB in general was pretty hostile toward events like festivals
