iCloud Keychain escrow data is encrypted by HSM clusters that have administrator keys destroyed; if Apple tried to compromise a keychain by installing malicious HSMs users would first get notified that their data had been lost due to failed/destroyed HSMs.
Trusted computing is a technical concept. People use Bitcoin because it’s provably secure against clearly outlined threats, not because they trust some vendor. Apple and a certain group of fans want to present iOS as a trusted computing platform for certain use cases, but it’s not.
Anyway, I see you’re just trolling here, so there’s no point talking to you.
