Paradox has the money. And there's the concept of defending your copyright or lessening your case in future suits that can make it worth the costs.Who's got the money to sue anybody over a fanbook somebody made in Publisher?
There's a difference between using fan goodwill from your work as a freelancer to convince them to give your Patreon some money, and using Patroen to make money off of something you're not supposed to make money off of. What's the functional difference between putting this up on Patreon, or putting it up on DTRPG as a PWYW book?Anyway, it's not like other freelance writers don't bank on goodwill from their work on licensed IP to finance their Patreons. I don't see how anybody loses anything here.
