If I’m sending encrypted mail to gmail, only that one mail is compromised once decrypted on gmail’s servers.

What? How? Most private email providers only support encryption like Proton to Proton or Tuta to Tuta. Emails sended to anything else stay unencrypted. And there’s no way you’re going to use this stupid password protection everytime, because if you do, then why would you even use email?

Do you only send mail to gmail users or something?

Almost everyone uses Gmail, Outlook, Yahoo or whatever. Unfortunately, not everyone are privacy concious like you and me.

smtp is no better or worse than xmpp, irc or whatever else if you have end to end encryption.

No, it’s not. Emails should not be used by political activists to communicate. Even the best email providers like Proton or Tuta can’t give you 100% protection and this activist arrest is the perfect example.
Email is the obsolete protocol, that should only be used to register on random websites and get authorization codes. For everything else you should use secure messaging apps.

Trusting law-abiding corporations to protect your privacy is fundamentally a bad idea, and as such, promoting Proton as a private alternative to Google

You can’t trust anyone, that’s true. But self-hosting your own 100% bulletproof MailCow server on 1984 VPS, which you pay for in Monero won’t make you any more private, because emails you send still end up on Gmail inboxes.
It’s simply unneccesary for normal user with not so high threat model. And if you’re a political activist, then why even using email instead of normal privacy communication solutions like SimpleX, Session or Briar?

I think that you should look at our world realistically. You can’t just go “fuck the goverment” mode and remain active as a corporation. Proton shared as less info as possible, but they couldn’t refuse to share it at all.

lol, lmao

I assume you don’t understand how law and authorities work, if this is funny for you. Proton is still one of the best private email providers. Period.

Why build a new browser in C++ when safer and more modern languages are available?

Ladybird started as a component of the SerenityOS hobby project, which only allows C++. The choice of language was not so much a technical decision, but more one of personal convenience. Andreas was most comfortable with C++ when creating SerenityOS, and now we have almost half a million lines of modern C++ to maintain.
However, now that Ladybird has forked and become its own independent project, all constraints previously imposed by SerenityOS are no longer in effect. We are actively evaluating a number of alternatives and will be adding a mature successor language to the project in the near future. This process is already quite far along, and prototypes exist in multiple languages.
