As for the recent Oculus/Facebook issues, I have clients that also have Facebook accounts as they post ads and information that I need to see, and a couple think I should do nothing but work on their projects--no eating, sleeping, exercise, or having fun. One very impatient client gets frustrated if I don't respond immediately to his Skype messages, even late in the evening. I made the mistake of sharing my sim-racing Youtube channel with one, and he expressed frustration when he saw I had posted a couple of videos over a weekend, during a rush project--the result of his lack of planning. If Facebook reports what I'm doing with my Rift, that could be an issue--hopefully this can be reliably turned off in the account settings, but I'd still feel the need to confirm this every time I'm using my Rift. I occasionally take a break during the day, maybe 2-3 times a week, and run a few laps on the simulator, especially if I'm having an issue with a project. I concentrate on some clean, fast laps for 15-20 minutes, then return to the work with better ideas.
Just to pick this up, as someone who had already linked my Oculus account to Facebook in readiness for Quest 2 (which I'm extremely happy with based on initial impressions), the options are already there to effectively keep anything you do in VR completely off of Facebook. Now I've never felt the need to check if it's actually working, as apart from very occasionally doing some testing at work I never even log in to the FB account for anything else, but all the necessary options are there.
