The Librem 5 offers hardware killswitches on the side of the phone, and the Pinephone offers hardware killswitches in the rear of the device after removing the backplate.
I'm on 3, because 1 & 2 don't function well enough as phones (need reliable MMS, better audio, and better battery life). The first two have hardware switches, the last is controllable by software I somewhat trust. All three have significant caveats. Once 1 or 2 work properly as phones (don't even need Android apps), I'll switch.
Purism is slowly correcting course regarding refund policies, but meaningful improvements take time. Also, the letter from "Purism" to Rossmann came from a Purism volunteer who had no authority to publicly represent the company.
Yup, but that doesn't change how much I trust the hardware. I'm never going to buy from them, but I do think their phone hardware is decent. If I buy a Linux phone, it'll be a PinePhone.
