I think that this cannot be stopped, copyright or not, the tool is too powerful and too useful. But I understand the moral dilemma: why would I, as a creator, be happy if someone is using my work to basically put me out of work? I think that the solution is easier than it seems. The real value websites like Getty provide is not the image in itself, but the labelling. Put the labels under a paywall and problem solved. For source code it's more complicated, but I guess that you could somewhat limit access to commit comments. In any case, the genie is out of the bottle.
