Did you mean that 99% doesn't need unencrypted mails, and 1% would love to have open bar access to the emails of others (to "fight against criminality", or to "offer" a personalized ad "experience")?
I could have just ignored the whole post but this idea is harmful and needed a reply. The idea that people don't need privacy needs to die.
It's not even like it is an argument against protonmail and it doesn't convince me that fastmail is better. Fwiw I don't use any of them, I don't know them, I self host my mails unencrypted but this last characteristic is a bug, not a feature.
