I am going to temper my expectations a bit, since the article is specifically singling out their clause on accessing additional games. But at the same time, I am huffing the hopium since Sony has upstreamed PlayStation controller drivers to the Linux kernel, so they might be receptive to supporting SteamVR, Steam Link or something equivalent, if possible. (No, before you ask, I’m not expecting Linux support on PSVR2.)
I dunno about non-driver anti-cheats like EAC but Genshin Impact’s kernel-level anti-cheat has been used to aid ransomware. Driver-level anti-cheat is certainly malware, that has been settled since Sony-BMG.
