The driver software has been completely taken over by Facebook's nakedly nefarious motivations. It's not even just spyware, or even malware; the term I would coin for it is "fuck-you-ware". Want to play the game you bought last year, on the headset you bought two years ago? Fuck you! Make an account first. We changed the rules and updated the software without asking you and now all your data are belong to us...
