The Semetic minorities like Silte and Gurage are pretty much Amhar from the people I’ve talked to, while the Cushitic ones like Sidamas are aligned with Oromos. Along with other minorities that have grudges against Ethiopianist regimesAs evident, Abiy isn’t a big supporter of the right of self-determination. It goes against his vision of a might Ethiopia dominated by Addis. However, given the recent troubles and the ongoing issues in the country, it’s unlikely that Abiy will open another can worm in the near future. Otherwise, he may be begging for his own demise.
Amharas have always been categorically against that clause. Their fellow Ethiopianist (mostly minorities) have been empowered and given more power, thanks to the right of self-determination, so I think some of them do reconcile being a nationalist with retaining that law to some extent.
Oromos may be Abiy current support base as he’s pandering to them, but many of them support article 39. This is despite them being fine with some do Abiy’s centralization of power (to Oromos) and furthering their own agenda. Alliances are not permanent in Ethiopia after all, so their position isn’t surprising.
Somalis wouldn’t entertain such a reform, but we don’t have much power or say in the federal arena, besides Abiy’s allies. Tigrayans are totally against it too and they will surely will pushback. What’s interesting is that despite the Tigrayan administration being installed by Abiy, they won’t hesitate to express their displeasure with the gov’t.
Recently, there were rumors that the recently settled Amharas in western Tigray (while their people are displaced) could be given a referendum using article 39, but the Tigrayan president openly objected to such a move.
Anything is possible in the future, but nothing of the sort will happen soon.
