1. The Russian position in 2014 was that the Ukrainian people in Donbas were being oppressed by the new Ukrainian central government.

2. There's a lot of domestic political/information suppression in Ukraine but I consider this somewhat normal for a nation in a pretty existential conflict.

3. The Ukrainian military is 70-80% conscripts, increasingly of the "forcibly mobilized" variety (look up "TCC busification" for examples), with almost all military-age males banned from leaving the country. Dudes are getting beaten up, stuffed into vans, and sent to trenches to eat Russian artillery and FABs (air-to-ground bombs)....against their will. I think that definitely counts as suppression.
