I understand it as a protest against copyright, or at least the abuses of it by the organisations in question.
Rejecting copyright is a perfectly legitimate position. It's not immature, nor does it have anything to do with the means of "getting content legally and quickly" that are currently available.
It's a movement I guess that is screaming for Hulu? Are most of those in this movement not in the US?
But again this the RIAA they are targeting as mentioned above any song you want to listen to is available on youtube through ur PC or their iPHone app.
