It seems to be people who've never heard of zines and think they're the same thing as Russet Noon or Another Hope. I think it's partly that people usually find zines on ebay, and they're often quite expensive. I've seen people suggest that, because the internet is available, any current zines must be done for nefarious profit-making purposes. (Which is interesting because I'll bet some of those same people prefer print books to ebooks.)
