It sounds more like a piece of protest than an actual license. Any arsehole could interpret the situation as "since this is software and not a human being, it isn't ackshuyally learning anything. So our usage of your content doesn't violate your license lol lmao".
I think that people are correctly angry at big tech calling dibs on whatever it wants, but misblaming it on AI. There are worse cases out there; have you heard about targeted advertisement, for example?
