I'm assuming the rule is around because FB knows it's targeting isn't 100% accurate and it might ruffle feathers if an ad claims you're something you're not. I don't see that specifically as nefarious.

Especially because FB tells me why I am being shown an ad already.

In the early days of COVID I was curious what the difference between types of viruses. e.g. how herpes and HIV hides in cells compared to viruses like influenza and SARS-CoV-2.

One of those sites clearly had Facebook integration because now Facebook is sure that I'm an HIV-positive gay man, with ads that correspond. It is one thing to get the ads but it would be a bit more overt if there was a text ad declaring that I was an HIV positive gay man.

People take offense at being told that there’s a machine labeling them, and would demand the right to revise or remove the machine-assigned labels. Facebook prevents that outcome by preventing disclosure of targeting characteristics.

See also this Show HN from /new for purging your complete set of labels, and ask why Facebook doesn’t build this into the site UI. https://news.ycombinator.com/item?id=27045374

(The link is broken, but apparently there's a page you can single-remove specific interests from, if you can find it.)

Wow, that item link points to a literally blank page. The site template is there but there isn't even a title header.

Sadly even the web archive's copy of the page has the empty version :(
