Your content is stolen for training the moment you put it up
It is an _incredible_ stretch to frame certificate transparency logs as "content" in the creative sense.
The whole purpose of this data is to be consumed by 3rd-parties.
It would be funny if your content disappeared when it was stolen.
If I give my content away for free, it can’t be stolen.
The point of putting up a public web site is so the public can view it (including OpenAI/google/etc).
If I don’t want people viewing it, then I don’t make it public.
Saying that things are stolen when they aren’t clouds the issue.
