One concern is that you can’t always trust the Wikipedia link. For example, in this edit [1] to the Equifax page, a spammer changed the link to a spam site. They’re usually fixed quickly, but it’s not guaranteed. So it’s a really neat project, but be careful about actually using it, especially for sensitive websites.
