There is a new e-ink minimalist phone called the Mudita Kompakt that has only a black and white display (can't watch porn in black and white) and lets you customize what apps are available on the device, so you can allow only shit like email, an rss feed for news, signal for messages, etc.
But the best part is it has a hardware killswitch for the GSM module, microphones, cameras, etc. Meaning you can now completely prevent kikes from tracking you when needed.
Challenge accepted. For real though, it's just an e-reader with a phone - I can't see that it will be popular enough to maintain security updates on it for very long, despite how novel the idea is.
