If SLR don’t want to work with the Heresphere guy, that’s their decision. The fact is that they are, as I understand it, the number one VR porn site by some distance. If they went all in on Heresphere, it would undoubtedly lead to greater sales for the guy who owns it and they don’t want him to use their content to sell his VR player. By not supporting Heresphere, they are keeping a lot of people off it and using their own player instead. If people desperately want to watch SLRO stuff on Heresphere, they can but SLR aren’t going to set up an API over there and make it easy for him to make extra money off the back of their content if they don’t want to.
As for VRB leaving? They can’t control what third party studios choose to do with their own content.
I’m not saying all this as some SLR shill, I complain often about the lack of variety in their content. Fair is fair though, some things they can’t control and sometimes you don’t do business with people you don’t like/trust. It’s as simple as that.
