Count me as another data point. I deleted my Facebook and Twitter accounts, and it has not affected my social or professional life in any noticeable way. I was worried I would lose access to my Oculus purchases, but I did not.

The straw that broke the camel’s back was reading my ads profile summary in Facebook settings. It claimed I was in “Established Adult Family Life with Children” or something similar. This was revolting. I was disturbed that Facebook seemed to know I was expecting a baby. I realized that Facebook was extracting far more value than it was giving, so I deleted my account.

I was genuinly sad when Facebook bought Oculus as I knew they would never be able to resist the temptation to add all kinds of data harvesting to it.

And so I have not yet bought my self a VR set. Thankfully Valve stepped up last year.

I clicked on "Interest Categories" deep in ad settings and FB is reporting an error. Is there another way to get at its assessment of me?

I actually had the opposite experience: my profile was so inaccurate. It said I had kids when I don't, for example.
