Gmail's upcoming self-destructing emails will require the recipients to click on a link and log in with their #Google accounts to see the content, if they are accessing via IMAP/SMTP.
Don't be fooled: Google's purpose is not to give us more confidentiality. They want all of their users to access their mailboxes via the Gmail app or their web interface, so they are creating a burden to the recipients and calling it “security” to convince people to adopt it.
@saltorito @miramarco Meh, #protonmail has its own share of problems... for starters their software is proprietary, not sure how someone could trust a so called encrypted email when we can't verify what their apps do on our devices.
@gutigen @saltorito @miramarco I would argue that you can check out the entire code. See https://github.com/ProtonMail?tab=repositories
@mawe @miramarco
Actually almost everything Google makes is open source and they contribute a lot to ecosystem, especiallu security-wise, so that's also not true (won't use their services though). If #protonmail was truly private and transparent platform they would commit to open source from the ground up. #proprietary software simply cannot be trusted.

You can argue, but only web client source code is there... meanwhile Android, iOS, imap bridge - all proprietary.
