I post in the voice of Christopher Walken
Really? What prevents Pathfinder or the OSR here? As far as I can tell nothing at all does, at most they end up having to share a bit of revenue with WotC.
No idea if Solasta (which I just looked up and know nothing about) is even using the OGL. According to WotC they are not covered by it even today however.
I am still trying to understand all of this, but it sounds like there is more to it than just that concern. But having to share revenue data and revenue isn't a small thing. That gives WOTC a lot of information about the hobby and about competitors. If you are a company making lots of revenue with a particular line, and you have to share that data with WOTC, it could mean WOTC sees that information and decides to launch its own line along the same idea. Plus you are just giving a rival information about your company you might not want to share for a host of reasons. But people like Estar seem to be expressing concerns about the license that are more about its impact on what you can make.
