Doesn’t really matter what you or anyone wants. Apple is held legally responsible for their clients data stored on their network. They, as a corporation, have made the decision to thus require enhanced security for their clients login credentials. If you don’t like that, then don’t make or use an AppleID and therefore don’t use Apple online services like iCloud.
It’s your choice which online services you sign up for and use. It is the choice of the company providing the service and thus legally responsible for your data stored on their systems as to what they decide is appropriate security for logins (minimum password lengths, minimum password complexity, password expiration, two factor authentication or whatever the company policy is for use of their online services).
It is is well known that systems protected solely by passwords are inherently less secure than those with additional login requirements. It is also well known that many people routinely use trivial and insecure passwords, forget them, share them when they shouldn’t and so forth. Since companies are the legally liable entity when personal or private data is breached, more and more companies are looking for ways to force people to take their own account security more seriously, or at least protect unauthorized access better then has been traditionally done in the past.
Apple is also very publicly dedicated to a privacy policy that ensures, as much as absolutely possible, that you, and only you, can access your private or personal data. They are deliberately designing their systems so their own people cannot get to and read your data, nor can law enforcement or any other person or agency unauthorized and un-enabled by you, the client and owner of the data. https://www.apple.com/privacy/
