They’ve said they’re paying out of pocket, though the only stat I’ve seen is that it’s “significantly” more than $20 a month (which… could be basically anything lol.)
There’s a thread here with that info: https://lemmy.blahaj.zone/post/1106021
Slightly related: I was looking recently at early issues of Dragon magazine on archive.org, and #3 has a section on women. The title is “NOTES ON WOMEN & MAGIC – Bringing the Distaff Gamer into D & D”.
It proceeds roughly how you’d expect from the title.
That doesn’t make it less open source, though.
It’s important to understand that those rules are now perpetually open and free to use/copy/modify. WotC truly relinquished any chance of trying to claw them back.
For 5e there is https://open5e.com/, although that is under the OGL.
Didn’t WOTC end up releasing that under a creative commons license?
I think it probably makes more sense to simply post about the game in a general community! (i.e. this one). If there’s a lot of involvement, then you can consider splitting off.
I think it’s a weirdly over-the-top response to the situation described here: https://www.polygon.com/23823516/dnd-dungeons-dragons-wizards-ai-art-controversy-bigby-presents-glory-of-the-giants
