I don't think everyone who listens to music is engaging with the music. People will be shocked that Rage Against the Machine is political despite listening to them for years.
My issue with SFV is entirely with the content that is more popular in the medium. I've seen SFV that promotes learning in bite-sized chunks and I've seen some that are entirely wholesome and uplifting. Just like some people can watch Jersey Shore, read Atlas Shrugged, or listen to mumble rap and I will consider that a waste.
I don't think I have the right to tell everyone what they can do with their time. So I don't support the condemnation of something just because I don't approve of it.
