AI Summary

The bug was filed to remove StartCom (StartCom) from Mozilla’s CA program, alleging a violation of Mozilla CA policy related to revocation of certificates believed to be compromised. The reporter stated that StartCom demanded additional payments, including from paying customers, to revoke certificates believed to be compromised. The reporter argued that revocation obligations under the Mozilla CA policy apply regardless of customer payments, and that charging may be acceptable for re-issuing but not for the revocation itself. Another participant pointed to bug 994033 and marked this bug as a duplicate. The bug’s resolution is listed as DUPLICATE, and the thread does not describe any separate remediation action by Mozilla or StartCom beyond the duplicate handling.
