This is excellent! Congratulations to the Purism Librem team for having a privacy vision and all the follow-through to create the phone. I'm buying one.
If you ever ask yourself "what can I do to improve privacy?" then considering trying the phone. The software is open source and there are plenty of areas for ongoing optimization, including subsystems such as security and graphics speed, and apps such as email, calendar, contacts, etc.
I'm not affiliated with Purism; I'm a big believer in the privacy goals and also in the team for their successful launch of a version 1 product to market. Kudos!
