It is not a matter of ethics. Do you think it is the priority for such corporations? It is a matter of PR. It takes a single "problematic" generated content to be framed as "Google is sexist/racist/supports animal abuse", etc. Statements related to ethics help in a few ways: holding secrets ("oh, we would love to share the models, but we cannot"), protecting against backslash (PR-wise, legal-wise), and PR on its own ("we are that ethical - see! it is even in our mission statement").
