I don’t think you know either, neither of us can confirm with certainty that he did not use Project Reds tools to built his integration. Key word being integration there.

It might be a completely standalone Installer so that he can keep you trapped in his ecosystem and on a subscription based service, but that has no relation at all to whether or not his program makes use of the tools project red offers to allow these integrations.

If they touch project reds tools at all to give you a good vr experience, then as much as it sucks, they are beholden to project reds rules. More obviously I’m bias as fuck and hate the idea that someone would force others to pay for a mod, especially one adding such a massive QoL feature to beloved games. But hey, if it comes out that he didn’t touch any of said tools at all, then he’ll be fine anyways. The dmca notices will go away and he’ll be free to continue being a drama queen about something else :).
