I'm not sure I understand what you mean... Do you think the OP makes money off of uncertainty, or the lawyers who are posting on reddit?They make money off of claims to uncertainty... and WOTC posts here. (Why no that isnt a conspiracy theory why ever would you ask?)
If it's the latter, that doesn't make sense to me. Most of the lawyers who are commenting don't work in copyright law (some of them live in other world countries and have some interest in US copyright law). So how could they make money off of uncertainty regarding US copyright laws on copyrighting TTRPG rulesets?
