For one thing, Lemmy used to have 65K at its peak, so yes we definitely have dropped since then.
But as for how much or even whether we've dropped within the last year - which the graphs show but as you deservedly are saying that you would like confirmation for - I suspect that the answer is that nobody knows, really.
Like lemm.ee used to be one of the largest instances - so where did that traffic "go"? Moreover, is it still being counted now, e.g. as part of the 65K total, or with the entire instance having shut down, are its counts now removed from both the numerator and denominator?
While that situation was over a year ago now, it does illustrate that I personally at least have no idea how these numbers shown in the graph are being calculated. Nor do I trust them in the slightest - e.g. I know that I personally make up at least 2 of those MAUs, and maybe more depending on the month examined. Lemmy servers used to be significantly less stable than they are now, so whenever one would become almost entirely unresponsive for a few days, many of us active on the Threadiverse at that time would simply hop over to another alt. Plus some of us like to experience features first-hand like what does PieFed offer, in comparison to Lemmy.
On the other hand, I have no other source of numbers, so I discussed what was presented in front of us. 65K down to 33+/-~7K is already a large enough difference that I believe that we have lost many users. Plus we can see them all over the place talking about how displeased they are with their experience while here - over on Reddit, and Bluesky, and I'm not going to look but presumably also X, Facebook, Insta, etc.
Whether these numbers are valid over the last single year or not... I cannot truly say. Although that alone seems quite telling, given how horribly Reddit is treating its user base lately - e.g. beginning to (or is it done for everyone already) shut down old reddit, and blocking people that use a VPN, etc. The fact that many more people are not coming here already should be sufficient for us to make inferences about our popularity, separately from precisely how many people are actively leaving the Threadiverse or not.
For example, read the comments at https://www.reddit.com/r/fossdroid/comments/1uiywal/should_we_switch_to_lemmy/. Copying and pasting a few that I had highlighted previously:
I tried switching to Lemmy a long time ago, but that place is toxic and full of weird people.
There are big pockets of radical tankie communities on Lemmy that like trolling and being toxic
There are a lot more reasons than this but having spent the last 3 years on the fediverse alternatives, and just seen the shit that happens over there, I feel very confident in saying it will not ever serve as a serious Reddit alternative. It will serve as something, but not Reddit
Lemmy is shit. So is reddit but Lemmy is shittier
Sadly, these seem representative of how people think of us here. You can see it for yourself too: simply browse most instances from an account without your existing blocks, in order to see what it is like from the eyes of a Redditor. Worse, they are primarily religious (Christian, Muslim, Mormon, whatever) centrists, and not only do they not FEEL welcomed here, but... in truth... they AREN'T ⁉️
