Basically all of the software that I write for projects like this is GPL by default, but I generally include a note (as in this case) that developers should contact me if the license doesn't work for them. I find this to be a good balance: those who wish to take my work and openly contribute their own work are free to do so, and those that don't need to contact the copyright holder. I don't think it's a lot to ask in this case, and I definitely don't think that licensing issues are what's holding back internet security here or otherwise.
