I am not greatly relieved by this post of Anthropic's. That said, they seem to have lines and are willing to stand by them; I don't see where OpenAI has done that. So, for now and from my point of view, the point goes to Anthropic.
Moving my subscription is not terribly consequential, but since the products are so similar and easy to substitute with one another for my uses, it seems best to participate in what in aggregate is a signal that is being noticed and commented on and interpreted to mean that a significant number of people who buy AI access do care about this.
