Big tech uses other public or "free" CC, etc knowledge bases to train ML models. Like Wikipedia as a training set for a GPT or word2vec model. Or using WikiData to seed a knowledge graph. Or training based on a common crawl dataset. All of these resources are used to make the assets that major tech companies use to make their products a lot smarter. They're built on the free labor of the rest of society.
Big tech reaps tremendous, society altering benefits from the free labor of others. And "training a model" seems to whitewash away the licensing concerns.
Shouldn't that be disconcerting whether we are developers or wikipedia editors?
