This is what is so frustrating to me as well! I have visited a few old subs to see where/if they were moving and the amount of people saying essentially “why would the mods do a useless protest” and “nobody cares about kbin/Lemmy nobody is going to switch” is so perplexing to me. I also get frustrated at “this change won’t affect me so I just want to sub opened” when I have seen it explained multiple times that a lot of the useful mod tools are built on these API calls so if you want to have well moderated subs, you want this to be worked out! And even without that, just the way that reddit is handling this whole situation sucks.
I think it is very plausible that the numbers only appear to be back to normal. I agree probably nothing will change but at the very least I am not using reddit any more - and I feel like I have seen a similar sentiment from other users of Lemmy/kbin.
