Purism scams their customers left, right, and center and have for effectively their entire existence. They should not be trusted, and their phone specs are basically from 2013 sold for $800.
So even if you're idealistic enough to pay $800 for a phone that'd be in a landfill if it didn't have hardware privacy features, Purism will take that trust you have in them and screw you over – delay you for as long as they need to/can/want with no recourse for a refund outside of maybe the courts. After which you hope you either get a functioning product or get good luck with a disorganized, opaque, scumfuck company like that.
