What if the CA certs are compromised, as was alluded to for GCP in the Snowden leaks?
All server security measures are irrelevant if every client req/res is dragnet siphoned off to NSA servers in plaintext. It would also afford the corporation deniability even if they were aware or involved.
This is why everything than can feasibly be E2EE (or performed locally) should be, unless the data is explicitly public. There are too many opportunities for compromise even when the provider has the best of intentions, and ruling class psychopaths aren't intentionally destroying democracy or implementing big brother.
