Sure, just show me the combined DnD/D&D or TTRPG community | magazine | group. It doesn't exist. There are a hundred, or a thousand, individual groups. That's not a whole community. That's a thousand fractal shards, each one with its own voices, independent of one another. Yes, occasionally they do share content or users, but that happens only rarely and with effort. TTRPG Network, Lemmy.ML, KBin.Social, Mastodon.Social, etc., all have various groups dedicated to RPGs. These groups are not able to be combined.
The inability of these groups to combine and independently organizing is a severe weakness of ActivityPub.
The more that happens, the more fractured the community becomes, and the easier it will be for a new centralized corporate platform to suck up users. That's how Reddit started in the first place, and how Twitter started. Heck, it's even how LJ started. You look at fractured elements of communities, and build a site for the whole community to come together.
I'm sure users will step forward if they care. Otherwise, it's just a campaign optimization at work. Limit the breadth of organic content to deepen the brand-friendly content and push more paid media into the feed.
