Even those who opted-into this data collection certainly didn't opt-in to it being posted publicly on Facebook?
Well the picture of the woman on the toilet is in the article, so it's fairly safe to say her privacy has been infringed.
It was infringed long before it was added to an article.
Pretty sure none of the users consented to photos of them on the toilet being posted on Facebook (and now a news article; wtf was the Tech Review thinking).
Face blurred, no way to see who it is (though I haven't checked for EXIF in the picture, that would be fubar). IMHO and I don't expect anyone else to share it, the picture drives the surveillance aspect home better than word would, though perhaps that makes more of a difference for people who don't ordinarily read Tech Review.
>...and I don't expect anyone else to share it,
...aha!
It is still mortifying to have a photo of you sitting on the toilet with your shorts down even if your face is blurred out. Yes, the damage has already done and this made the article even more compelling, but I don't think it was necessary or appropriate.
