This irks me A LOT and is simplified to the point of being incorrect, yet lots of people here make the same logical errors.

Protecting the contents of peoples devices and accounts with strong encryption and hardware security is great for the individual and protects them from thieves and governments alike. If Apple designed their devices so that they cannot unencrypt the content without the users secret passsword, that's sensible for a lot of users.

But E-Mail Addresses and Accounts are derivatives of your identity and companies should have ways of returning your accounts to you, even if the content is lost, in case of stolen identities.

I am pretty paranoid about this stuff and only store private data using encryption and on trusted devices running mostly hardened FOSS software (Graphene OS, Fedora Secure Blue, OpenSuse MicroOS, etc.) and my backups are rcloned encrypted to the cloud. Yet for my most important e-mail that is bound to paypal, banking, shopping etc. I use posteo. They do this exactly right. I have personally tested contacting their support to return access to the e-mail address in case of a "lost password". After some validation, they returned access for it to me, but the encrypted content was unrecoverable. That is exactly what any responsible company should do.

The people suing didn't turn on E2E encryption. The government could already get access to their data via subpoena. Apple already has access to their data as well. Apple just doesn't want to be forced into doing basic customer service.
