In an ideal world, all AI-generated content would be required to be labeled as such, but I think that is very unlikely to be enforced (or even enforceable for that matter).
I think on iNat generative AI could even be completely disallowed. Apart from the numerous ethical concerns there are regarding generative models and the companies and decisions behind them, this is another reason. People can do to their images whatever they want to make them more visually appealing, but iNat’s primary function is the recording and identification of organisms. That shouldn’t dissuade anyone who wants to to take and/or edit visually appealing photographs, but if the visual appeal comes at the cost of IDability, then that just kinda defeats the whole purpose of putting it onto iNat, does it not?
I do think copyright concerns are a large part of it as well, though. The issue is both, IMO. While big for-profit platforms may benefit from unregulated genAI–with its negative effects conveniently being hidden behind the huge dollar signs in the eyes of their share holders–places like iNat provide a chance to initiate a more reasonable stance towards them, so I really think there should be some clear statement soemwhere.
