It's an incredibly fuzzy statement, really.

You can copy copyrighted material you download for your own use and the use of your friends. You can't copy it to a different website and distribute it further on the "open web". You can modify material provided for download in your own home for any purpose you wish but unless that modification is in the category "fair use" (a small part, a parody, etc) you can't distribute it freely on the web either.

His statement might mean this but it could mean a zillion other things too (what does "it is fair use" mean? etc)

Whether using randomly obtained copyrighted material to "train" an LLM and then selling the output of that LLM is "fair use" seems like so far another "gray area" and the foggy statement seems oriented to reducing awareness of that situation.

Legally you cannot actually do the first thing without permission. The fact that it was technologically impossible to stop, and the damages would be impossible to prove, didn't make it a legal right.
