I’m saying it’s “just” talk, meanwhile I’m ready, today, to but better if you can provide.
A 200 dollar Xiaomi phone or a used pixel phone is at least 10x more powerful than the pinphone. After unlocking the bootloader and rooting it, you can use termux and have a linux environment at hand. You can even install a DE and access it. Enjoy. The plus is that you don’t lose any compatibility with android apps .
I really hope you don’t go around telling anyone that is criticizing something to just make a better version, do you ? You don’t need to be chef to say bad food is bad. To make it easier to understand let’s transpose it again : There’s a novel motor design that is free and open source. Someone make a car using it and sell it but the car can’t go beyond 20km/h and has a range of 50km. Would you tell anyone that says it’s unusable to just make a better one ??
