> Other Email providers such as Tuta which also offer encrypted emails, were forced to install a backdoor. As soon as the police arrive, every future email sent to the account in question is copied unencrypted without the person being informed.

Important caveat: Tuta was required by a court to provide police with access to a customer's _unencrypted_ emails (ie regular SMTP mail). The police had also asked for a backdoor to Tuta's E2E emails, and that request was rejected by the courts.

But the idea behind Tuta and Proton is that emails are encrypted when they arrive in the inbox. The fact that emails sent between Tuta users are still safe offer little added value because distribution is far too limited. The reason people choose such a provider is that they do not want the authorities to have access to their mailbox, but this is undermined by a backdoor. Switzerland is much better off in terms of the legal situation in this area.
