I guess WGRZ doesn’t think much about local professionals, even if they are requesting a favor from them.
Unfortunately, they’re not alone. I’ve been asked by other media groups from the Buffalo News, to the BEE Newspapers for permission to use media, and rarely do they manage to credit it properly, or at all. Hell, it’s often an impressive step if they even bother to ask to use it. Larger media organizations simply don’t care about the work of others apparently. As long as they get what they need in the moment.
