Pretty much everything is trained on copyrighted content: machine translation software, TWDNE, DALL-E, and all the GPTs. Software people are bringing this up now because it's their ox being gored. It's the same as when furries got upset about This Fursona Does Not Exist.[1][2]

To expand on your argument, pretty much every person is trained on copyrighted content too. Doesn't make their generated content automatically subject to copyright either.

yeah, except that Oracle and google have way more lawyer power than furries artists.

You have no idea how much money they make. Some of them have payment plans for commissions.

This is an argument for why this is a bigger problem, not a smaller one.

If it's BSD-licensed, the encumbrance doesn't matter much.
