> How does the authentication prove that the intended recipient is the one who has clicked on the link and should be able to view?

You log in with a Google account associated with the recipient address. You prove you control the email by putting in a code Google sends you.

> What happens if the email is forwarded with the link?

They can't open it because they don't have access to the Google account associated with your email address.

> What should one do to forward the email to someone without this encryption?

Obviously, encrypted emails are not meant to be forwarded. Nothing prevents you from taking a photo though. Maybe copy and paste will work.

> Organizations may need ways to store, archive and manage received email content from others.

Organizations can't control how they receive information. It doesn't matter what they want in this regard. If a judge orders them to do something about it, that's for the judge to figure out.

> I don’t understand what problem this solves for organizations and how.

It keeps messages private. You don't see why organizations in e.g. health care, law, or the military want increased privacy of messages in a way that is super easy to use? And where recipients can't accidentally forward sensitive messages? A lot of this is determined by compliance requirements too.
