The L5, as already said by others, is practically a gnome phone.
Unfortunately this is a really nuanced space though - you have to deal with the following that will divide different groups:
- libhybris vs running mainline
- lack of support for various drivers when running mainline
- ubiquity of android and iOS apps, some of them fundamental to peoples jobs, money access and social lives
- components with no open-source equivalents (modem, wifi, bluetooth .. etc)
