I think we need more details to really help.
The free software position though isn't against you making money from an
e-publication. They aren't against you charging for software either. It might
be difficult to charge for software where anybody who gets at it has the
right to redistribute though.
What I say to this is stop being lazy and think about the consequences. Not
just for your readers, but for you as well. Think about all the possible
solutions and business models that could solve this problem without
implementing DRM.
You can charge for a publication without implementing DRM. If the charge is
reasonable it is less likely people will bother hunting it down elsewhere. If
the amount of piracy is astronomical than go with an advertising based
publication method and make it so easy to get at without paying for it that
it makes no sense to go elsewhere.
If you can't/don't want to sell advertising there are other easily
implementable solutions like: Google AdSense (amongst others). By not
restricting the publication to paid subscribers you will gain the advantage
of additional revenue from advertising.
There are other ideas too like have a release date for the magazine and
artificially delaying the release if a certain amount of money is not raised
by that date. You would still release it no matter what though. It just would
be an extra X days. You would then publish the front page and the article
index page to entice users to contribute. Once you find there is a story you
want to read it's a lot more likely you you will contribute financially.
