Part of the point of ReactOS is that it can use the existing Windows drivers for existing hardware, so every driver that doesn’t work is because of a bug that needs to be fixed. Even if no one uses a particular piece of hardware, the same bug might have stopped another driver for another piece of hardware working.
Something else worth noting is that instance admins do a lot more moderation than Reddit admins did, so the burden on the moderators for individual communities can be smaller. lemmy.ml in particular has a reputation for having admins who actively intervene a lot.
