That's quite the list. Maybe post them separately, so others can upvote the ones they think are interesting.

By now Proton has quite the suite of products. While I think this is great, I'm also familiar with the "just make one thing good" argument. Can you tell us more about the synergy between Proton VPN and other Proton products? Are these mostly technical or related to marketing/business strategy/UX/something else?

I think I understand why Proton doesn't integrate contacts with other systems (like mobile contacts). It introduces the risk of leaking data to a less secure system outside of Proton's control. Yet, contact integration might be in the top 3 frequently requested features. I'm therefore curious:

How does Proton feel, in general, about compromising between privacy/security vs less secure but (understandably) highly requested convenience features?
