In case anyone else is curious:
Why is Chrome taking action?
Certification Authorities (CAs) serve a privileged and trusted role on the Internet that underpin encrypted connections between browsers and websites. With this tremendous responsibility comes an expectation of adhering to reasonable and consensus-driven security and compliance expectations, including those defined by the CA/Browser TLS Baseline Requirements.
Over the past six years, we have observed a pattern of compliance failures, unmet improvement commitments, and the absence of tangible, measurable progress in response to publicly disclosed incident reports. When these factors are considered in aggregate and considered against the inherent risk each publicly-trusted CA poses to the Internet ecosystem, it is our opinion that Chrome’s continued trust in Entrust is no longer justified.
