"I would think stepping down has some risks at the moment because you don’t know who’s replacing you"
You could literally give an notice to the Reddit admin or whoever you are in contact with that you disagree with the way they handle things, that you are gonna step down but would like to pick your replacement personally.
Reddit would likely agree because it means that they don't have to search for a mod themselves and if the mods have such a strong connection with the community than finding a replacement should be in the realm of possibility.
The whole striking saga gives a whole lot of "We tried nothing and we are all out of ideas" vibe.
