10k people are still playing the game after the decline. It's just the fat cutting out after all the newbies who aren't all that good at fighting games left to go somewhere else. It's a common thing, in this genre.
Since you're the expert on multiplayer though how about you tell us how you'd reverse this decline? Turn SF6 into a battle royale GaaS perhaps?
I am legitimately not joking, I'm going to pester you for the entire day for your response on this.

Because your thread just exposes that you don't seem to get niche multiplayer games in general. I would love to see your solution to make what's already a quite casualised, mainstream friendly SF6 even more casualized to retain the ginormous player counts it had at launch.
Not true, in Steam SF6 has 20-25K daily active users, which basically is more than the rest of the relatively recent fighting games combined. Unless I miss something, SF6 is the most popular/played fighting game in Steam's history.
And in Street Fighter IV and V series PC was between 1/5 and 1/6 of the sales. This means that if in SF6 PC also is 1/5 and 1/6 of the total, we're talking about 100K-150K daily active users (mostly on them on PS looking at the tradition of the genre, Capcom and most top multiplayer publishers/games).
Street Fighter 6 daily users on Steam:
All games have a lifetime DAU (daily active users) peak in the few launch days and then heavily tank, with some minor peaks for important marketing pushes like the release of big updates, free weekends, big tournaments or price drops, etc.
In this case we saw SF6 had a big player retention -way better than in the other games of the genre- because the drop after the launch wasn't that big as in the rest of the games of the genre: the percentage of the launch peak players who continued in the game is bigger than in the other games of the genre. It means that on average players like SF6 more and continue more engaged than in other games of the genre.
The userbase -as in any other game- slowly declined after the lunch peak until got steady in 20-25K DAU with a couple minor peaks for the two new character releases. And declined more slowly than in other games of the genre.
This is Street Fighter 5 in Steam instead:
Its largest peak, the launch one was 15K, and half a year later was at around 1.5K and remained during a few years in around 1.5K-2K with small peaks, and later improved to 2.5K-3.5K until SF6 got released and SFV userbase basically died shortly after, as soon as in a few months its players moved to SF6.
Mortal Kombat 1
After its first month its DAU went down from the 40K launch peak to 7.3K, remained around 7-8K and later went down to around 4-5K
Mortal Kombat 11 got 2-3K DAU with peaks during years until it got a bump in 2023 going up to 4-5K.
Tekken 7 got basically 4-7K DAU with peaks:
Dragon Ball Fighterz (best selling ARC System Works game ever), got 1.5-2.5K DAU with peaks on Steam:
Guilty Gear Strive had around 2-3K with peaks.
