A TRO like that is based on the company loudly declaring that revoking will cause real damage. That means their use of certificates is incompatible with the web PKI rules and ecosystem. That means they need to be migrated out ASAP, with every certificate authority refusing to take their business.
Make that series of consequences clear, and companies will stop trying that trick.
Use of a TRO protects you short term, but results in having to migrate to a new CA medium term. You can't stop them from using TRO's but you can make it not worth it.
The other option would be building in a way to revoke other CA's individual certificates if there's some consensus on them being compelled to not revoke them. Not sure if the status quo or this would be more dangerous, but if a TRO can compel a CA to not sign a revocation, can it also compel to sign a certificate?
If running a private CA or self-signed certificates are even viable, then there are plenty of other workarounds that can be put in place (i.e. not updating the CRL so the software doesn't know about revocations).
If a CA's terms and legal documentation aren't tight enough to prevent a court from compel them to sign a certificate, that CA clearly cannot be trusted. Hopefully that issue can be fixed by writing clearer terms and better agreements, like people have been telling Digicert to do, but perhaps that's not possible at all. In that case, either the company should move to a jurisdiction where that kind of nonsense isn't possible, or it should be removed from global trust stores all together.
You say that and yet Teams has 320 million people using it, and I bet almost none of them enjoy the experience. Sometimes you just have to work with what you're given. Given "incompetence", we might as well throw in all of Azure.
> Let Salesforce figure out how to automate certificates, they've been in the business for long enough.
That might be true for DV, but there's classes of certificates that take at least weeks to obtain, think BIMI VMC or codesigning.
Yeah, there are tons of companies who chose Teams as a vendor (because it's bundled with other stuff), and inflict it on their employees. It was still absolutely their choice.
