That was very strange for me as well, as the original stated goal of OpenAI was to decentralize power. It looks like instead of that they just want to be one more of the few powerful entities.
If they thing OpenAI made isn't interesting enough of a discovery without its data (because it's all arbitrary anyway), but is very useful to spammers as a piece of code, OpenAI has truly achieved the 200% opposite goals they were looking for.
I mean the Faceswap people have the same problem. They could give less a shit about porn. But that's what people used it for.
