"To conclude this discussion, Mozilla is denying the Japanese Government
ApplicationCA2 Root inclusion request. I'd like to thank everyone for your
constructive input into the discussion, and I'd like to thank the Japanese
Government representatives for their patience and work to address issues as
they have been discovered. I will be resolving the bug as "WONTFIX"."
"We are preparing to revoke certificates immediately, rather than waiting for certificates issued prior to 2017 to expire.
However, even if we revoke those certificates, if your judgment is not affected and our request is rejected, there is no point in doing it.
Please let us know if our request will be accepted by revoking all the certificates we issued prior to 2017."
That quote by itself is a reason to drop a CA. If you're only going to do the things you're REQUIRED to do when you're threatened with rejection/revocation, then you shouldn't be a CA to begin with. The arrogance shown in that thread is appalling.
Lol
