Any CA who believes that the courts in their country could not prevent them from revoking certificates is confused at best. It's true that DigiCert could have refused to cooperate with Alegeus and fought the court order instead of cooperating with them to rotate the certificates ASAP. But that would have taken a lot longer than 5 days, even if they eventually won. If the CA Browser Forum has such a strong security interest in swift revocation, it's hard to see how further delaying the revocation in order to provoke a legal battle promotes that interest.
