In brief, FANO wants Amhara rule in Ethiopia to be restored. Things like Amharic language primacy, Orthodox Christians having more rights then non-Orthodox Christians, Amharas owning large swaths of land in the south of Ethiopia and them settling it, basically they want everything that happened in Ethiopia after the year 1974 to go away.
Reactionaries through and through.
Here I found a small commentary from a Tigrayan during the rise of
Ginbot-7 and the
National Movement of Amhara which are both preceding organizations to the current FANO revolt, which formulated their ideology during Woyane tyranny.
