Seems fair, they don't have to offer that and this is just one of many archives of public DNS data.

I think you're conflating "fair" with "strictly permissible under the law". Lawful isn't the same as being ethical, decent, or "fair".

All this data is so public that offering any kind of removal option is pretty pointless.
