Most people probably didn't pin the certificate. I think that the problem was caused by developers configuring their application to trust only the DigiCert Root CA. This usually happens beacuse some applications don't use by default the root CA bundle of the underlying OS to authenticate TLS connections, but require you to put each Root CA certificate in a trust store (ex. Java). Some devs probably added just the Digicert root CA and forgot about it. These kind of changes with certificate are always kind of tricky, because they usually work very reliably until they don't. |
