The great thing about a community is that any one person can find a particular area of interest and focus on it.
My focus was, "Lets stop doing business with these troll companies and their affiliates until they change their business practices." So every chance I get I mention other options beyond Getty and Masterfile. I have convinced about a half dozen clients to stop using istockphoto and Getty images and switch to Pond5. I have spoken at several L.A.-area user group meet-ups about the practice of copyright trolls and what you can do to protect yourself. I'm sure to make it clear who these "bad actors" are and to suggest alternatives.
I also created and maintain a list of sites that claim to offer public domain or free-to-use images here at
http://www.extortionletterinfo.com/forum/getty-images-letter-forum/list-of-public-domain-stock-footage-companies/. Although some feel these sites don't indemnify you if someone claims you are infringing on their image, I would point out that this is the same case with most (if not all) microstock companies.
Certainly better public relation tools would be a welcome addition. I'm sure if you put together great content, Matt can help you get it published. I guess we are all familiar with Nike's slogan by now...
