I've seen a few comments asking to change images on answers because of copyright issues. I'm wondering what the response to this should be.
This answer uses a single image from this page illustrate the answer which has been attributed to bidet.org which is a business selling bidets.
Would this normally be considered fair use?
The comment under the answer says it isn't but I don't see the reason. They say they don't have permission or a license but they are not required for fair use. If you had permission or a license, there wouldn't be any reason to invoke fair use.
If this is a copyright violation, would editing the post stop it being one?
Often the suggestion is to edit the post. Would this stop the answer from violating copyright? The image is still in a few places including the edit history, and data dumps. If there was a violation would we need to remove all copies of the content?
