Legal safety is (part of) the reason companies have "trust and safety" teams. The problem here is that AI training is probably not actually a copyright issue, some people just wish it was and are trying to manifest one by complaining. (Similar things exist in online artist communities with rules like "no reposting without crediting the artist" - they think if they just keep telling everyone this is the rule it'll become one.)
