John Gruber argues that public data should not be automatically included for AI training, as individuals should have the right to opt-out rather than opt-in. He emphasizes the importance of ownership and copyright, stating that publishing content on the web does not give others the right to use it for AI training. He also raises concern about individuals posting content that they do not own on social media, making it difficult for the original creator to control how their content is used. This highlights the need for individuals to have more control over how their content is used for AI training.
