It hasnt suffered a lot - so far. But it is like Chinese water torture - drip drip drip, bit by bit it is slowly eroding, some subs far worse affected than others. Most niche subs and local subs are still going strong, but I suspect after a while they will start to collapse one by one as moderators leave and users come here, or to discord or other alternatives

As much as I want to see reddit burn, I think we are more likely to see a slow, almost imperceptible crumbling away
