When your opsec "expert" recommend you Matrix because it is federated.

Ask him/her what server they use.

Matrix.org? they are not opsec experts😆

Paying for Protonmail is a sign of stupidity of ignorance or both.

They scan e-mails and own private keys.

If you are not imbecile start using GPG + for instance Thunderbird.

It is not a rocket science!

Or just start using Delta Chat with e-mail for FREE👈

No your keys no your data

And...

"unencrypted messages sent from external providers to your Account, or from Proton Mail to external unencrypted email services, are scanned "
