PieFed and Mbin are both different implementations of the ActivityPub Protocol just like Lemmy. Although I doubt this graph includes either of them, despite how many left Lemmy for Piefed when Lemm.ee went down.
I looked and PieFed adds another ~1600 monthly active users and Mbin a further ~700 to the mix. PieFed starts out its chart with single digit user counts and ends with three orders of magnitude growth, so definitely not flat at all, though stable over the last few months.
