Booting pure gnu Linux with telephony enabled, wow it would be like a dream coming true. Fremantle ui on top of a gnu Debian ( I know Fremantle is a Debian based) with lot of packages to play with, no problems related to lack of development, updates. But general public still doesn't want pure Linux they want 4gb ram, 16 mp camera, security breaching OSes, they don't care about privacy and it that's y we guys are suffering . I show my friends Nokia n900, sailfish device all the time and they say " u r not a VIP" even computer teachers teaching in KV schools I used to work with they said the same thing " we r not VIP" so we should not worry about our privacy. The last option what I truely believe is a DIY rasp pi based phone but all we can do now is wait and watch.
