"Club" has been used to describe subscription products for as long as I can remember. Columbia House/BMG's mail order CD business were called record clubs, for example. There was (is?) also the Book of the Month Club and plenty of other "X of the month" clubs that probably existed way before the world wide web.
Perhaps "joining a club" sounds more positive/marketable than "subscribing to a mail order service."
