Fundamentally, if I own a property I should be able to allow/disallow access to anyone as I see fit, and charge appropriately. If I make money, I'm still obligated to pay taxes on it (therein, I imagine, lie the problems).
So I'd claim that AirBnB and Uber are helping push for more sane regulations which allow free-er markets, while Grooveshark was basically just short of directly-stealing the content of others to profit on themselves.
That said, I'd still rather have Grooveshark than not, because I personally don't care so much about the record-companies rights - but certainly the government should be there to help uphold the rights of individuals and businesses, which, alas, means legal trouble for Grooveshark.
