@Tutanota Wants to scan? People should assume they are ignoring any settings and are scanning them anyway.
The thing is, on one hand I don't think I had a personal conversation via email in years. All I got is automated emails (transactional and marketing), and those are unlikely to support encryption (PGP or any other standard) and even if they support, it might not always work due to backyard compatibility.
Business, on the other hand, has the issue of companies using Google and/or Microsoft suites (like mine).
Most of my personal conversations go via WhatsApp (that should be encrypted but... yeah) and Mastodon (E2EE is in the works). Sadly no one uses Signal here, despite it being the most popular FOSS messaging app with safe and enforced E2EE.
