Those are good things to ask prior to using it, but thats just the beginning.

• If the training data matches what you would look up on the internet anyway, is it a deal breaker?
• If it cannt be used for production, what about for organizational purposes? Documentation? Resource tracking? Upstream changes? Merging considerations? Security auditing?
• It sounds like you would rather do the coding part, correct me if I'm wrong. This way you have full control of the license. For someone who isn't a coder, they would probably have to consider that the code it generates could closely resemble an existing licensed work since the models are trained on open-source data.
• I think the getting dumber argument is going to depend on the user, and its not an LLM issue specifically. You could definitely bypass the thinking process, but you could also make it explain things step by step, which could also accelerate learning stuff.

But you're right, to each their own.
