Is ProtonMail lying about their encryption? In response to Nadim Kobeissi and LiveOverflow

As the most popular encrypted email provider, ProtonMail has been criticized for false security promises and weak guarantees of its end-to-end encryption infrastructure. Can be ProtonMail's marketing of their Swiss-based email service justified? The results might SHOCK you!

Why is ProtonMail more secure than Gmail https://protonmail.com/blog/protonmail-vs-gmail-security/

The problem with ProtonMail’s webmail service is that each time you go to sign in to their website, you have to completely trust ProtonMail that the javascript that your browser runs is correctly implementing PGP and is not trying to steal your private keys and read your messages. This problem is limited with smartphone apps, because each new version of an app has to be signed by the author and the platform – which in this case is ProtonMail and Google Play Store or Apple App Store. With these apps, users can verify whether they received the same binary for a particular version as everyone else.
Because of the differences in the levels of trust, webmail services are objectively less secure than desktop and smartphone apps...
