I never said it sends your plaintext password.

It says it 'encrypts' your password, because it needs to access your Keychain. The dialog says this, but there is no way to opt out.

You are 100% wrong.

When logging into iCloud, they show a pop-up asking for the local password to the computer. And then they upload that password to the iCloud servers.
