Probably because it's not a "security blunder of the highest order".
Equifax was a "security blunder of the highest order". This is an it-happened-to-Facebook-and-Google "shit, some sensitive info ended up in internal logs" blunder where there's no reason to suspect the PINs actually leaked out of the company. And even if they did, a PIN on its own is not sensitive information - unlike a password, it's just a 4 digit number, there's only 10000 of them. And unlike SSNs, they can be changed. I can tell you my PIN is 1077 and what on earth are you going to do with that information?
