Exactly this. I'll attempt to speak for my kin here, I'm currently a student and while interested in Hacker Monthly, I couldn't justify paying (subscribing?). I entered my details in the form and hopefully I am eligible. If the product is interesting and useful I would have no problems paying (either when I'm no longer a student or even before that). I'm sure there are others like me and this seems like a case of "get them hooked young and they will be customers for life".
