Proton mail is a paid service. It comes with the bridge. The bridge is not extra.

Free-tier Proton Mail may charge for the bridge. I don’t know, I don’t use free-tier Proton Mail.

Bridge is part of the Proton Mail paid service. They advertise it right here: https://proton.me/mail. It's not unreasonable to say that if you are paying for Proton Mail, you would expect the bridge to work considering they advertise it as a feature

Free-tier ProtonMail does not have the privilege to use this buggy bridge.
