Can you share the warning? I made a public page and would say it was not clear to me this was a consequence of doing that. The warning as I remember it (a month ago) makes it sound like the information on this page is going to be public -- not - oh yeah the email addresses of everyone who edited this page will also be leaked.
It's definitely weasel wording. And moreover, it's honestly tiring to constantly have these weasel words carrying such weight, and then jackasses getting bent out of shape that they aren't given the benefit of the doubt anymore.
Please also especially clarify that IDs of contributors will be public. Meh is good, but this was a bit too simple.
There is a way to mitigate this. Re-hash and cache the page to be meta-less for public URLs. I guess that requires a huge amount of coding for a team that has not built the product from the ground up. But I feel like a "copy and paste" could fix that (remove author data).
