I'm sorry I don't have anything to say that's terribly comforting about this. If you want to prevent your code from being used by people for purposes other than those of which you approve, then you will be, to that extent, closing up your license, even if the provision is weaker than the (obviously too strong) "I reserve the right to revoke your right to use this software and its source code if I determine that your project contravenes (provisions from my value system)".
The BSD license obviously won't prevent this sort of abuse, nor will the GPL. The GPL might thwart their desire to close up their source, because they're distributing the software to their users, which would at least give their users some sort of hook into their code, and to a limited extent, to their servers and protocols. But there's no morals clause in the GPL.
I'm less familiar with the Artistic license, but I see no language in there that prevents this sort of abuse of your good will.
