Not sure why you're being downvoted. Software running on the user's machine has no business keeping secrets from the user. This "feature" is the antithesis of computing freedom as we know it.

Trusted computing is at least salvageable. The issue is not the technology but who owns the keys. If users can install their own keys, the technology will empower them with increased security. SGX cannot be used to empower the user like this. It's specifically designed to protect software from the user.
