Does any employer get a certificate from any of the CAs you listed to MITM their internal networks?

The listed companies are employers. I think they all have self-managed CAs.

Yes, but surely the listed companies don't use their public and globally trusted CAs to MITM their internal networks. I hope they have another internal CA to allow them to MITM their internal Network.
